Solar and Wind Energy Start to Win on Price vs. Conventional Fuels
2014-11-23, New York Times
Posted: 2014-12-01 02:14:25
http://www.nytimes.com/2014/11/24/business/energy-environment/solar-and-wind-...

For the solar and wind industries in the United States, it has been a long-held dream: to produce energy at a cost equal to conventional sources like coal and natural gas. That day appears to be dawning. In some markets renewable generation is now cheaper than coal or natural gas. Utility executives say the trend has accelerated this year, with several companies signing contracts, known as power purchase agreements, for solar or wind at prices below that of natural gas, especially in the Great Plains and Southwest, where wind and sunlight are abundant. Those prices were made possible by generous subsidies that could soon diminish or expire, but recent analyses show that even without those subsidies, alternative energies can often compete with traditional sources. According to a study by the investment banking firm Lazard, the cost of utility-scale solar energy is as low as 5.6 cents a kilowatt-hour, and wind is as low as 1.4 cents. In comparison, natural gas comes at 6.1 cents a kilowatt-hour on the low end and coal at 6.6 cents. Without subsidies, the firms analysis shows, solar costs about 7.2 cents a kilowatt-hour at the low end, with wind at 3.7 cents. It is really quite notable, when compared to where we were just five years ago, to see the decline in the cost of these technologies, said Jonathan Mir, a managing director at Lazard, which has been comparing the economics of power generation technologies since 2008.

Michigan Governor Rick Snyder signed a bill on Tuesday that will keep electric carmaker Tesla Motors from selling its cars directly to consumers in the state, home to the biggest U.S. automakers. Snyder said in a letter to members of the state House of Representatives on Tuesday that the measure merely "clarifies" existing law not to allow direct manufacturer-to-consumer retail sales. Those sales, he said, must be made through franchised dealers. Michigan becomes the fifth U.S. state to keep Tesla from easily selling cars directly to consumers. In all of those states except Michigan, Tesla operates "galleries" where consumers can view Tesla cars but cannot discuss prices, take test drives or order cars. Michigan has gone a step further, said Diarmuid O'Connell, Tesla vice president of business development, and will not allow even the informational galleries. Tesla, which has challenged some of the long-held conventions of auto industry, wants to set up its own sleek stores rather than to sell through a franchised dealer network. The Michigan measure, passed 38-0 in the state's Senate and 106-1 in the House, does not mention Tesla by name. But, O'Connell said, the legislation clearly is addressed to the company. O'Connell said the bill was pushed through the legislature without chance for public debate because well-connected auto dealers did not want a public airing of the state's policy. Detroit-based General Motors on Tuesday said it supported the new measure.

Wind Power Blows Away Coal and Gas in Nordic Countries
2014-10-17, Scientific American/Reuters
Posted: 2014-10-20 18:46:16
http://www.scientificamerican.com/article/wind-power-blows-away-coal-and-gas-...

Wind power is blowing gas and coal-fired turbines out of business in the Nordic countries, and the effects will be felt across the Baltic region as the renewable glut erodes utility margins for thermal power stations. Fossil power plants in Finland and Denmark act as swing-producers, helping to meet demand when hydropower production in Norway and Sweden falls due to dry weather. The arrival of wind power on a large scale has made this role less relevant and has pushed electricity prices down, eroding profitability of fossil power stations. "Demand for coal condensing power in the Nordic power market has decreased as a result of the economic recession and the drop in the wholesale price for electricity," state-controlled Finnish utility Fortum said. Nordic wholesale forward power prices have almost halved since 2010 to little over 30 euros per megawatt-hour (MWh) as capacity increases while demand stalls on the back of stagnant populations, low economic growth and lower energy use due to improved efficiency. "The Nordic system price will likely more often clear well below the production cost for coal fired power production," said Marius Holm Rennesund Oslo-based consultancy THEMA. "This will, in our view, result in mothballing of 2,000 MW of coal condensing capacity in Denmark and Finland towards 2030," he added. Adding further wind power capacity at current market conditions could lead to power prices dropping towards as low as 20 euros per MWh, the marginal cost for nuclear reactors, Rennesund said.

http://abcnews.go.com/International/wireStory/japans-shinkansen-bullet-train-...

Zipping cross-country in a super-high speed train has become commonplace in many countries these days, but it was unheard of when Japan launched its bullet train between Tokyo and Osaka 50 years ago Wednesday. The Shinkansen, as it's called in Japan, gave a boost to train travel in Europe and Asia at a time when the rise of the automobile and the airplane threatened to eclipse it. The first bullet train, with its almost cute bulbous round nose, traveled from Tokyo to Osaka in four hours, shaving two and a half hours off the 513-kilometer (319-mile) journey. The latest model, with a space-age-like elongated nose, takes just two hours and 25 minutes. The first Shinkansen had a maximum speed of 210 kilometers (130 miles) per hour. The fastest trains previously, in Europe, could reach 160 kph. Today's bullet trains, in Japan and elsewhere, have reached and in some cases exceeded 300 kph (186 mph). By average speed, China has the fastest train in the world, averaging 284 kph. Turkey last year became the ninth country to operate a train at an average speed of 200 kph. South Korea and Taiwan also operate high-speed systems in Asia. The fastest train in the U.S., Amtrak's Acela Express, averages 169 kph (105 mph) on a short stretch between Baltimore and Wilmington, Delaware. Shanghai launched a German-built maglev train in 2004 on a 30-kilometer route between the city and the airport. It can hit 430 kph (267 mph). A Japanese maglev train in development has topped 500 kph (310 mph) in tests.

Note: Gas and oil interests have lobbied hard to keep Americans wedded to their cars and stop the development of high-speed trains.

Scientists Create Very First Solar Battery that Stores its Own Power
2014-10-03, Science World Report
Posted: 2014-10-08 20:38:51
http://www.scienceworldreport.com/articles/17672/20141003/scientists-create-v...

Scientists may have created the very first solar battery. Researchers have succeeded in combining a battery and a solar cell into one hybrid device, which could be huge in terms of renewable energy capture and storage. "The state of the art is to use a solar panel to capture the light, and then use a cheap battery to store the energy," said Yiying Wu, one of the researchers, in a news release. "We've integrated both functions into one device. Any time you can do that, you reduce cost." The key to the new device is a mesh solar panel, which allows air to enter the battery. There's also a special process for transferring electrons between the solar panel and the battery electrode; inside the device, light and oxygen enable different parts of the chemical reactions that charge the battery. "Basically, it's a breathing battery," said Wu. "It breathes in air when it discharges, and breathes out when it charges." The mesh solar panel forms the first electrode. Beneath the mesh is a thin sheet of porous carbon, which acts as the second electrode, and a lithium plate, which acts as the third electrode. Between the electrodes are layers of electrolyte to carry electrons back and forth. During charging, light hits the mesh solar panel and creates electrons. Then inside the battery, electrons are involved in the chemical decomposition of lithium peroxide into lithium ions and oxygen. The oxygen is released into the air, and the lithium ions are stored in the battery as lithium metal after capturing the electrons. The findings could be huge in terms of creating sustainable energy for powering a variety of devices. Currently, the researchers are continuing to move forward in improving the efficiency of the battery and the amount of power the panel can absorb and convert. The findings are published in the journal Nature.

The sports car that runs on saltwater
2014-09-01, Daily Mail (U.K.)
Posted: 2014-09-26 12:07:11
http://www.dailymail.co.uk/sciencetech/article-2739768/The-sports-car-runs-SA...

Sports cars may not have the best reputation for being environmentally-friendly, but this sleek machine has been designed to reach 217.5 mph (350 km/h) using nothing but saltwater. Its radical drive system allows the 5,070lbs (2,300kg) Quant e-Sportlimousine to reach 0-60 mph (100 km/h) in 2.8 seconds, making it as fast as the McLaren P1. After making its debut at the 2014 Geneva Motor Show in March, the saltwater technology has now been certified for use on European roads. The 920 horsepower (680 kW) Quant e-Sportlimousine uses something known as an electrolyte flow cell power system to power four electric motors within the car. It works in a similar way to a hydrogen fuel cell, however, the liquid used for storing energy is saltwater. The liquid passes through a membrane in between the two tanks, creating an electric charge. This electricity is then stored and distributed by super capacitors. The car carries the water in two 200-litre tanks, which in one sitting will allow drivers to travel up to 373 miles (600km). NanoFlowcell AG, a Lichtenstein-based company behind the drive, is now planning to test the car on public roads in Germany and elsewhere in Europe as the company prepares for series production. It claims the technology offers five times the energy capacity of lithium-ion batteries of the same weight. 'We've got major plans, and not just within the automobile industry,' says NanoFlowcell AG Chairman of the Board Professor Jens-Peter Ellermann. 'The potential of the NanoFlowcell is much greater, especially in terms of domestic energy supplies as well as in maritime, rail and aviation technology.'

The coming era of unlimited and free clean energy
2014-09-19, Washington Post blog
Posted: 2014-09-26 12:02:08
http://www.washingtonpost.com/blogs/innovations/wp/2014/09/19/the-coming-era-...

In the 1980s, leading consultants were skeptical about cellular phones. The handsets were heavy, batteries didnt last long, coverage was patchy, and the cost per minute was exorbitant. The experts are saying the same about solar energy now. They say that solar is inefficient, too expensive to install, and unreliable, and will fail without government subsidies. They too are wrong. Solar will be as ubiquitous as cellular phones are. Futurist Ray Kurzweil notes that solar power has been doubling every two years for the past 30 years as costs have been dropping. He says solar energy is only six doublings or less than 14 years away from meeting 100 percent of todays energy needs. By Kurzweils estimates, inexpensive renewable sources will provide more energy than the world needs in less than 20 years. In places such as Germany, Spain, Portugal, Australia, and the Southwest United States, residential-scale solar production has already reached grid parity with average residential electricity prices. In other words, it costs no more in the long term to install solar panels than to buy electricity from utility companies. The prices of solar panels have fallen 75 percent in the past five years alone and will fall much further as the technologies to create them improve and scale of production increases. By 2020, solar energy will be price-competitive with energy generated from fossil fuels on an unsubsidized basis in most parts of the world. Within the next decade, it will cost a fraction of what fossil fuel-based alternatives do. Despite the skepticism of experts and criticism by naysayers, there is little doubt that we are heading into an era of unlimited and almost free clean energy.

Grid parity: Why electric utilities should struggle to sleep at night
2014-03-25, Washington Post blog
Posted: 2014-09-26 11:58:15
http://www.washingtonpost.com/blogs/innovations/wp/2014/03/25/grid-parity-why...

Whats good news for those concerned with climate change, and bad news for electric utilities? Thats grid parity. It exists when an alternative energy source generates electricity at a cost matching the price of power from the electric grid. As grid parity becomes increasingly common, renewable energy could transform our world and slow the effects of climate change. Advances in solar panels and battery storage will make it more realistic for consumers to dump their electric utility, and power their homes through solar energy. A 2013 Deutsche Bank report said that 10 states are currently at grid parity: Arizona, California, Connecticut, Hawaii, Nevada, New Hampshire, New Jersey, New Mexico, New York and Vermont. Germany, Spain, Portugal and Australia have reached grid parity. This shift has benefited from a dramatic drop in the price of solar panels, which dropped 97.2 percent from 1975 to 2012. As solar energy gets cheaper, traditional electric utilities are doing the opposite. The cost of maintaining the electric grid has gotten more expensive, but reliability hasnt improved. If customers leave electric utilities, it starts a downward spiral. Fewer customers will mean higher rates, which encourages remaining customers to jump ship for a solar-battery system. Energy upstarts are led by forward thinkers with disruptive track records and eyes on societys big problems.

John D. Rockefeller built a vast fortune on oil. Now his heirs are abandoning fossil fuels. The family whose legendary wealth flowed from Standard Oil is planning to announce on Monday that its $860 million philanthropic organization, the Rockefeller Brothers Fund, is joining the divestment movement that began a couple years ago on college campuses. In recent years, 180 institutions including philanthropies, religious organizations, pension funds and local governments ... have pledged to sell assets tied to fossil fuel companies from their portfolios and to invest in cleaner alternatives. In all, the groups have pledged to divest assets worth more than $50 billion from portfolios. Some say they are taking action to align their assets with their environmental principles. Others want to shame companies that they believe are recklessly contributing to a warming planet. Ultimately ... their actions, like those of the anti-apartheid divestment fights of the 1980s, could help spur international debate, while the shift of investment funds to energy alternatives could lead to solutions to the carbon puzzle. At the Rockefeller Brothers Fund, there is no equivocation. The fund has already eliminated investments involved in coal and tar sands entirely while increasing its investment in alternate energy sources. The family has also engaged in shareholder activism with Exxon Mobil, the largest successor to Standard Oil. Members have met privately with the company ... in efforts to get it to moderate its stance on issues pertaining to the environment and climate change. They acknowledged that they have not caused the company to greatly alter its course.

Sun and Wind Alter Global Landscape, Leaving Utilities Behind

Of all the developed nations, few have pushed harder than Germany to find a solution to global warming. And towering symbols of that drive are appearing in the middle of the North Sea. They are wind turbines, standing as far as 60 miles from the mainland, stretching as high as 60-story buildings and costing up to $30 million apiece. On some of these giant machines, a single blade roughly equals the wingspan of the largest airliner in the sky, the Airbus A380. By years end, scores of new turbines will be sending low-emission electricity to German cities hundreds of miles to the south. It will be another milestone in Germanys costly attempt to remake its electricity system, an ambitious project that has already produced striking results: Germans will soon be getting 30 percent of their power from renewable energy sources. Germanys relentless push into renewable energy has implications far beyond its shores. By creating huge demand for wind turbines and especially for solar panels, it has helped lure big Chinese manufacturers into the market, and that combination is driving down costs faster than almost anyone thought possible just a few years ago. The changes have devastated its utility companies, whose profits from power generation have collapsed. The word the Germans use for their plan is starting to make its way into conversations elsewhere: energiewende, the energy transition. Worldwide, Germany is being held up as a model, cited by environmental activists as proof that a transformation of the global energy system is possible.

Why is solar booming?
2014-08-01, Time Magazine
Posted: 2014-09-09 06:35:02
http://time.com/3204258/wall-street-goes-green

The clean-power revolution is for real. Wind and solar have gotten much cheaper, less novel and more predictable. Green electricity is no longer avant-garde; it has produced more than half of new U.S. generating capacity this year. Wind has tripled since 2008, while solar is up 1,200%. This is terrific newsfor homeowners who reduce their electric bills by going solar, ratepayers whose utilities save them money by buying wind power, and the planet. But theres a deeper message. People assume the future of clean energy depends on gee-whiz technological innovations: better solar panels and wind turbines, cheaper batteries and biofuels. And we will need those advances in the long term to cut carbon emissions 80% by 2050. But the biggest advances in the near term are likely to be boring financial innovations. The innovation that launched the sunshine revolution was the solar lease, which has helped homeowners and businesses install rooftop systems without having to plunk down tens of thousands of dollars up front. Now they can sign 20-year contracts with no money down to lease panels from installers like SolarCity or Sunrun, then make payments out of the savings on their electric bills. Now were moving into the next phase of the renewable revolution. Those 20-year leases look a lot like mortgages, auto loans or other financial instruments that Wall Street routinely packages into securities. And Wall Street has begun to package solar contracts into securities. The market for commercial solar securities has grown from less than $1 billion to $15 billion since 2008.

Researchers Develop Transparent Solar Concentrator That Could Cover Windows, Electronics
2014-08-24, Huffington Post
Posted: 2014-09-09 06:33:42
http://www.huffingtonpost.com/2014/08/24/transparent-solar-concentrator_n_570...

Scientists at Michigan State University announced this week the creation of a transparent luminescent solar concentrator that could turn windows and even cellphone screens into solar-power generators. The material works by absorbing light in the invisible spectrum (ultraviolet and near infrared) and then re-emitting it in the infrared. The infrared light is then channeled to the edge of the clear surface, where thin strips of photovoltaic cells generate the power. Because we cannot see infrared or ultraviolet light, the material remains transparent even while concentrating sunlight. Previous luminescent solar concentrators have been developed, but they emitted light in the visible spectrum, creating a stained-glass effect. No one wants to sit behind colored glass, Richard Lunt, who leads the lab researching this new technology, said. The new technology is promising, but needs to be made more efficient. Researchers say that the solar conversion efficiency is around one percent. Ideally, this could be increased to more than five percent. Luminescent solar concentrators are less efficient than traditional photovoltaics, which absorb a larger range of wavelengths, but they could allow energy harvesting on surfaces that would otherwise never be used to generate power. The transparent technology could be used in a variety of applications, Lunt said, and its affordability means it has the potential for eventual commercial or industrial use. Ultimately we want to make solar harvesting surfaces that you do not even know are there, he said. The researchers' findings were published in the journal Advanced Optical Materials in July.

Revolution in use of resources in order to meet demand
2014-08-16, San Francisco Chronicle (SF's leading newspaper)
Posted: 2014-08-25 07:59:20
http://www.sfgate.com/business/article/Revolution-in-use-of-resources-in-orde...

For years, pundits have warned that the world's soaring population ... will usher in an age of scarcity. We already have a hard time supplying 7 billion people with food, with energy, with water. What happens when we hit 9 billion, the Earth's projected population in 2050? Stefan Heck and Matt Rogers say the resources are there - and the way we use them is about to undergo radical change. In their new book, Resource Revolution, they argue that information technology and advanced materials science, combined with new business models, will enable companies and societies to do far more with far less. It will be, they claim, a jump in productivity and efficiency greater than anything seen before. Heck, who teaches resource economics at Stanford University, and Rogers, a director of the McKinsey & Co. consulting firm, spoke with The Chronicle. Q: So current forecasts call for the world to add 2 billion people by 2050. Do we have the resources to give them a decent standard of living? Rogers: Take an example California faces right now - water. If you look at the next 20 years, we need to double the economic output for every unit of water we use. The good news is, in agriculture, we have a set of technologies where we can get much higher yields with the water that's available. Q: How about energy? Rogers: This resource revolution affects both how we produce and consume energy. With the dramatic increases in fuel economy we're seeing, from electrification and hybrids but also improvements in the internal combustion energy, you see an ability to improve the use of energy.

Three-Wheeled Elio Gets Closer to Going on Sale
2014-08-15, ABC News/Associated Press
Posted: 2014-08-25 07:57:42
http://abcnews.go.com/Business/wireStory/wheeled-elio-closer-sale-24991923

Your next commuter car could have two seats, three wheels and get 84 miles to the gallon. Elio Motors wants to revolutionize U.S. roads with its tiny car, which is the same length as a Honda Fit but half the weight. With a starting price of $6,800, it's also less than half the cost. Phoenix-based Elio plans to start making the cars next fall at a former General Motors plant in Shreveport, Louisiana. Already, more than 27,000 people have reserved one. Elio hopes to make 250,000 cars a year by 2016. Because it has three wheels two in front and one in the rear the Elio is actually classified as a motorcycle by the U.S. government. But Elio Motors founder Paul Elio says the vehicle has all the safety features of a car, like anti-lock brakes, front and side air bags and a steel cage that surrounds the occupants. Drivers won't be required to wear helmets or have motorcycle licenses. The Elio's two seats sit front and back instead of side by side, so the driver is positioned in the center with the passenger directly behind. The Elio has a three-cylinder, 0.9-liter engine and a top speed of more than 100 miles per hour. It gets an estimated 84 mpg on the highway and 49 mpg in city driving. Elio keeps the costs down in several ways. The car only has one door, on the left side, which shaves a few hundred dollars off the manufacturing costs. Having three wheels also makes it cheaper. It will be offered in just two configurations with a manual or automatic transmission and it has standard air conditioning, power windows and door locks and an AM/FM radio. More features, such as navigation or blind-spot detection, can be ordered.

Oil a key motive for U.S. air strikes in Iraq
2014-08-12, San Francisco Chronicle (SF's leading newspaper)
Posted: 2014-08-18 07:44:20
http://www.sfgate.com/business/bottomline/article/Oil-a-key-motive-for-U-S-ai...

This week's U.S. air strikes in northern Iraq are being accompanied with an undertow of "it's all about oil" talk. Take for example, Columbia School of Journalism Dean Steve Coll's observation in The New Yorker, that "Obama's defense of Erbil (capital of the semiautonomous Kurdish region) is effectively the defense of an undeclared Kurdish oil state." It's no secret that Iraqi Kurdistan has an abundance of oil reserves, nor that U.S. oil companies, like [Chevron] are busy exploring there. Chevron has three "production sharing contracts" with the Kurdish government, covering a combined 444,000 acres, north of Irbil, where it's in the early testing and drilling stage. And it likes what it sees. Asked for an update, a Chevron spokesman said Monday, "We continue monitoring the situation. We remain in regular contact with the Kurdistan Regional Government and are dedicated to supporting the (Kurdistan Region of Iraq) in developing its natural resources." A potentially bigger worry for both Chevron and the Kurds .. could be if Iraq did stabilize and unite, with Kurdistan under its umbrella. For Chevron ... a new arrangement in Iraq could entail the renegotiation of contracts it has with the Kurds, which by the way, Baghdad refused to recognize. Kurdistan's oil pipeline via Turkey continues to pump out oil - 120,000 barrels per day.

Oil companies fracking into drinking water sources, new research shows
2014-08-12, Los Angeles Times
Posted: 2014-08-18 07:42:46
http://www.latimes.com/nation/la-na-fracking-groundwater-pavillion-20140811-s...

Energy companies are fracking for oil and gas at far shallower depths than widely believed, sometimes through underground sources of drinking water, according to research released [on August 12] by Stanford University scientists. Fracking involves high-pressure injection of millions of gallons of water mixed with sand and chemicals to crack geological formations and tap previously unreachable oil and gas reserves. Fracking fluids contain a host of chemicals, including known carcinogens and neurotoxins. Fears about possible water contamination and air pollution have fed resistance in communities around the country. Fracking into underground drinking water sources is not prohibited by the 2005 Energy Policy Act, which exempted the practice from key provisions of the Safe Drinking Water Act. But the industry has long held that it does not hydraulically fracture into underground sources of drinking water because oil and gas deposits sit far deeper than aquifers. The study, however, found that energy companies used acid stimulation ... and hydraulic fracturing in the Wind River and Fort Union geological formations that make up the Pavillion gas field and that contain both natural gas and sources of drinking water. Thousands of gallons of diesel fuel and millions of gallons of fluids containing numerous inorganic and organic additives were injected directly into these two formations during hundreds of stimulation events, concluded Dominic DiGiulio and Robert Jackson of Stanfords School of Earth Sciences.

NASA approves 'impossible' space engine design that apparently violates the laws of physics and could revolutionise space travel
2014-08-04, The Independent (One of the UK's leading newspapers)
Posted: 2014-08-18 07:31:45
http://www.independent.co.uk/news/science/nasa-approves-impossible-space-engi...

In a quiet announcement that has sent shockwaves through the scientific world, NASA has cautiously given its seal of approval to a new type of impossible engine that could revolutionize space travel. In a paper published by the agencys experimental Eagleworks Laboratories, NASA engineers confirmed that they had produced tiny amounts of thrust from an engine without propellant an apparent violation of the conservation of momentum; the law of physics that states that every action must have an equal and opposite reaction. NASAs engineers have tested an engine known as a Cannae Drive, a machine [that] uses electricity to generate microwaves, bouncing them around inside a specially designed container that theoretically creates a difference in radiation pressure and so results in directional thrust. In an ordinary engine the rocket moves forward as fuel is flung backwards - the momentum of the rocket (a measure of both its mass and velocity combined) is 'conserved' because it is moved from the rocket to the fuel. However, with the Cannae Drive there is no fuel - the microwaves aren't expelled from the engine. NASAs scientists tested a version of the drive designed by US scientist Guido Fetta and found that the propellantless engine was able to produce between 30 and 50 micronewtons of thrust a tiny amount (0.00003 to 0.00005 per cent of the force of an iPhone pressing down when held in the hand) but still a great deal more than nothing.

Solar has won. Even if coal were free to burn, power stations couldn't compete

Last week ... the wholesale price of electricity in Queensland fell into negative territory in the middle of the day. For several days the price, normally around $40-$50 a megawatt hour, hovered in and around zero. Prices were deflated throughout the week, largely because of the influence of one of the newest, biggest power stations in the state rooftop solar. Negative pricing moves, as they are known, are not uncommon. But they are only supposed to happen at night, when most of the population is mostly asleep, [and] demand is down That's not supposed to happen at lunchtime. Daytime prices are supposed to reflect higher demand, when people are awake, office buildings are in use, factories are in production. That's when fossil fuel generators would normally be making most of their money. The influx of rooftop solar has turned this model on its head. The impact has been so profound, and wholesale prices pushed down so low, that few coal generators in Australia made a profit last year. Hardly any are making a profit this year. State-owned generators like Stanwell are specifically blaming rooftop solar. The problem for Australian consumers [comes] in the cost of delivery of [electricity] through the transmission and distribution networks, and from retail costs and taxes. This is the cost which is driving households to take up rooftop solar, in such proportions that the level of rooftop solar is forecast ... to rise sixfold over the next decade. Households are tipped to spend up to $30bn on rooftop modules. It is not clear how centralised, fossil-fuel generation can adapt. In an energy democracy, even free coal has no value.

Elon Musk Takes on Carbon With Solar, Battery Bets

The energy world is not keeping up with Elon Musk, so he's trying to take matters into his own hands. Musk, chairman of the solar installer SolarCity, announced [on June 17] that the company would acquire a solar panel maker and build factories "an order of magnitude" bigger than the plants that currently churn out panels. Musk is also a founder and the CEO of the electric vehicle maker Tesla Motors, which is planning what it calls a "gigafactory" to supply batteries for its cars. In both cases, Musk's goal is to make sure that the components critical to his vision of the future electric cars and solar energy are available and cheap enough to beat fossil fuels. Musk's future customer could ignore traditional energy companies completely. They'd have SolarCity panels on their roof that would generate enough power [to] charge up a Tesla [car] in the garage. A Tesla battery could then power the home at night with stored solar power. Musk has made a career of thinking far into the future. He is also the CEO of SpaceX, the rocket company with an ultimate goal of enabling people to live on other planets. SolarCity says it won't try to turn out more of the garden-variety panels now clogging the market. Instead, it wants to make panels that are more efficient, and make them at a low cost in huge factories in order to reduce the overall cost of solar electricity. Just as he drew customers to electric vehicles by making sleek, fast sports cars, Musk wants to attract homeowners to solar with pretty panels. "We want to have a cool-looking aesthetically pleasing solar system on your roof," he said.

Silicon Valley embraces open source as a moneymaker

Open source is going commercial. Once an esoteric philosophy that called for people around the world to collectively create and give away software, Silicon Valley is increasingly embracing the open source ethos as a way to make money. To expand the small market for electric cars, Tesla Motors CEO Elon Musk this week said he would share the company's technology with competitors. He follows industry leaders like Google, which has long allowed outside companies to customize its mobile operating system at no charge. Even Facebook is extolling the virtues of open source, which enables outside programmers to spot security flaws and helps preserve a spirit of innovation. As defined by the Open Source Initiative, the phrase ... means people not only can access and modify software code but redistribute it for free. The valley is starting to sense that enforcing patents doesn't always make sense. "Patents are so incompatible with the open source software philosophy," said Daniel Nazer, a staff attorney with the Electronic Frontier Foundation. That's Musk's mantra. The Tesla CEO didn't decide to give away his company's technology because he is a nice guy. Instead, Musk realized that electric cars won't gain mass acceptance if he is the only one making them. "Tesla Motors was created to accelerate the advent of sustainable transport," Musk said this week. "If we clear a path to the creation of compelling electric vehicles, but then lay intellectual property land mines behind us to inhibit others, we are acting in a manner contrary to that goal."
