Patents Secured for Revolutionary Nuclear Fusion Technology
2020-02-24, Popular Mechanics
Posted: 2020-03-23 19:07:32
https://www.popularmechanics.com/science/a31080902/fusion-energy-hydrogen-boron/

Scientists in Australia are making some astonishing claims about a new nuclear reactor technology. Startup HB11, which spun out of the University of New South Wales, has applied for and received patents in the U.S., Japan, and China so far. The company's technology uses lasers to trigger a nuclear fusion reaction in hydrogen and boronpurportedly with no radioactive fuel required. The laser doesnt heat the materials. Instead, it speeds up the hydrogen to the point where it (hopefully) collides with the boron to begin a reaction. You could say we're using the hydrogen as a dart, and hoping to hit a boron, and if we hit one, we can start a fusion reaction, managing director Warren McKenzie [said]. He says HB11's approach is more precise than designs that use heat to approach fusion because in those reactors, everything is heated in the hope that something will collide. When the lucky hydrogen does fuse with a boron particle, the reaction throws off helium atoms whose lack of electrons means theyre positively charged. Its this charge that the device gathers as electricity. The overall idea was developed by UNSW emeritus professor Heinrich Hora. Horas design seeks to not just compete with, but replace entirely the extremely high-temperature current technologies to achieve fusion. These include fussy and volatile designs like the tokamak or stellarator, which can take months to get up to functionality and still spin out of working order in a matter of microseconds.

Carbon emissions fall as electricity producers move away from coal
2020-03-09, The Guardian (One of the UK's leading newspapers)
Posted: 2020-03-16 21:35:26
https://www.theguardian.com/environment/2020/mar/09/carbon-emissions-fall-as-...

Carbon emissions from the global electricity system fell by 2% last year, the biggest drop in almost 30 years, as countries began to turn their backs on coal-fired power plants. A new report on the worlds electricity generation revealed the steepest cut in carbon emissions since 1990 as the US and the EU turned to cleaner energy sources. Overall, power from coal plants fell by 3% last year, even as Chinas reliance on coal plants climbed for another year to make up half the worlds coal generation for the first time. Coal generation in the US and Europe has halved since 2007, and last year collapsed by almost a quarter in the EU and by 16% in the US. The report from climate thinktank Ember ... warned that the dent in the worlds coal-fired electricity generation relied on many one-off factors, including milder winters across many countries. Dave Jones, the lead author of the report, said governments must dramatically accelerate the electricity transition so that global coal generation collapses throughout the 2020s. The cheapest and quickest way to end coal generation is through a rapid rollout of wind and solar, he said. The report revealed that renewable wind and solar power rose by 15% in 2019 to make up 8% of the worlds electricity. In the EU, wind and solar power made up almost a fifth of the electricity generated last year, ahead of the US which relied on these renewable sources for 11% of its electricity. In China and India, renewable energy made up 8% and 9% of the electricity system, respectively.

The Pacific Gas and Electric Company (PG&E) has diverted over $100 million from safety and maintenance programs to executive compensation at the same time it has caused an average of more than one fire a day for the past six years killing over 100 people. PG&E is the largest privately held public utility in the United States. A new research report shows that 91% of PG&E stocks are held by huge international investment management firms, including BlackRock and Vanguard Group. PG&E is an ideal investment for global capital management firms with monopoly control over five million households paying $16 billion for gas and electric in California. Between 2006 and the end of 2017, PG&E made $13.5 billion in net profits. Over those years, they paid nearly $10 billion in dividends to shareholders, but found little money to maintain safety on their electricity lines. A 2013 Liberty Consulting report showed that 60% of PG&Es power lines were at risk of failure due to obsolete equipment and 75% of the lines lacked in-line grounding. Between 2008 and 2015, the CPUC found PG&E late on thousands of repair violations. A 2012 report further revealed that PG&E illegally diverted $100 million from safety to executive compensation and bonuses over a 15-year period. In November, 2018, the PG&E caused Camp fire burned 153,336 acres, killing 86 people, and destroying 18,804 homes, business, and structures. PG&E has caused some $50 billion in damages from massive fires started by their failed power lines.

Renewable capacity set for 50% growth over next few years, IEA says
2019-10-21, CNBC News
Posted: 2019-12-31 02:29:06
https://www.cnbc.com/2019/10/21/renewable-capacity-set-for-50percent-growth-o...

Renewable power capacity is forecast to increase by 50% between 2019 and 2024, the International Energy Agency (IEA) said. According to its Renewables 2019 market report, the increase will amount to 1,200 gigawatts (GW) and be driven by drops in cost and what the IEA described as concerted government policy efforts. Capacity refers to the maximum amount that installations can produce, not what they are currently generating. In 2018, renewable capacity hit just over 2,500 GW. If the IEAs forecast plays out, it would bring total renewable capacity to approximately 3,700 GW by 2024. Solar photovoltaics (PV) are due to make up nearly 60% of the expected rise, with the onshore wind sector accounting for 25% and offshore wind responsible for 4%. Photovoltaic refers to a way of directly converting light from the sun into electricity. The IEA said that distributed solar PV systems installed on commercial buildings, homes and in industry would make up nearly half of the increase in the solar PV market. Overall, renewables share in worldwide power generation is seen growing from 26% now to 30% in 2024. For 2019, renewable power capacity additions are seen increasing by 12% following a stall last year. Growth this year is being driven by solar PV, which has benefited from rapid expansion in the European Union, a stronger Indian market and an installation boom in Vietnam. Growth in the onshore wind sector is also cited as a contributing factor.

Alabama Power fees on solar challenged
2019-11-16, Miami Herald/Associated Press
Posted: 2019-12-02 21:48:48
https://www.miamiherald.com/news/business/article237436404.html

When Jim Bankston installed solar panels on his Tuscaloosa home, he estimated it would trim his electricity bill, and the savings would eventually offset the cost of the hefty investment. After it was running, he noticed fees on his Alabama Power bill that he didnt understand and learned there was a $5-per-kilowatt capacity charge on customers who use solar panels to produce a portion of their own electricity. I am having to pay them just to use the photons that are hitting my own roof, Bankston said. He had estimated the system would eventually pay for itself in 20 years. With the fees included, he said it could be twice that. Its discouraging the use of solar, said Keith Johnston, managing attorney for the Southern Environmental Law Centers Birmingham office. We call it a solar tax. The fee is based on the size of the solar system, so a five kilowatt system would have a monthly fee of $25. The average solar panel setup for a home costs about $10,000, according to the environmental law center. The fees add another $9,000 over the 30-year-lifespan of a system, dramatically increasing a homeowners cost and reducing any financial benefit they see from solar, the law group said. The issue of fees has arisen in New Mexico, Arizona and other states, causing clashes between renewable energy proponents and utilities. A power company in Iowa unsuccessfully pushed lawmakers to approve a fee that would require a homeowner with an average solar array to pay about $27 a month.

Note: Unlike many countries which are subsidizing solar power as a clean energy source, some places in the US are discouraging solar by taxes like this. For more along these lines, see concise summaries of deeply revealing news articles on government corruption from reliable major media sources.


A decade of renewable energy investment, led by solar, tops USD 2.5 trillion
2019-09-05, United Nations Environment Programme
Posted: 2019-09-16 17:40:02
https://www.unenvironment.org/news-and-stories/press-release/decade-renewable...

Global investment in new renewable energy capacity over this decade 2010 to 2019 inclusive is on course to hit USD 2.6 trillion, with more gigawatts of solar power capacity installed than any other generation technology. This investment is set to have roughly quadrupled renewable energy capacity (excluding large hydro) from 414 GW at the end of 2009 to just over 1,650 GW when the decade closes at the end of this year. Solar power will have drawn half USD 1.3 trillion of the USD 2.6 trillion in renewable energy capacity investments made over the decade. Solar alone will have grown from 25 GW at the beginning of 2010 to an expected 663 GW by the close of 2019 enough to produce all the electricity needed each year by about 100 million average homes in the USA. The global share of electricity generation accounted for by renewables reached 12.9 per cent, in 2018, up from 11.6 per cent in 2017. This avoided an estimated 2 billion tonnes of carbon dioxide emissions last year alone a substantial saving given global power sector emissions of 13.7 billion tonnes in 2018. Including all major generating technologies (fossil and zero-carbon), the decade is set to see a net 2,366 GW of power capacity installed, with solar accounting for the largest single share (638 GW), coal second (529 GW), and wind and gas in third and fourth places (487 GW and 438 GW respectively).

https://www.cnbc.com/2019/07/15/scotland-has-produced-enough-wind-energy-to-p...

Wind turbines in Scotland generated 9,831,320 megawatt hours between January and June 2019, WWF Scotland said Monday. The numbers, which were supplied by WeatherEnergy, mean that Scottish wind generated enough electricity to power the equivalent of 4.47 million homes for six months. That is almost double the number of homes in Scotland. Up and down the country, we are all benefiting from cleaner energy and so is the climate, Robin Parker, climate and energy policy manager at WWF Scotland, said in a statement Monday. These figures show harnessing Scotlands plentiful onshore wind potential can provide clean, green electricity for millions of homes across not only Scotland, but England as well, Parker added. By 2030, the Scottish government says it wants to produce half of the countrys energy consumption from renewables. It is also targeting an almost completely decarbonized energy system by 2050. As a whole, Europe is home to some of the worlds most ambitious wind energy projects. September 2018 saw the official opening of the Walney Extension Offshore Wind Farm in the Irish Sea. With a total capacity of 659 MW, its currently the worlds largest operational offshore wind farm and capable of powering nearly 600,000 homes in the U.K..

U.S. Renewable Power Capacity Surpasses Coal For The First Time
2019-06-10, Forbes
Posted: 2019-07-22 18:13:58
https://www.forbes.com/sites/rrapier/2019/06/10/u-s-renewable-power-capacity-...

The revolution in renewable power hit a new milestone in April. Last week the Federal Energy Regulatory Commission (FERC) released it's latest Energy Infrastructure Update (EIU), with data through April 2019. According to ... the non-profit SUN DAY Campaign, which analyzed the data, "that was enough to push renewable energy's share of total available installed U.S. generating capacity up to 21.56%. By comparison, coal's share dropped to 21.55% (down from 23.04% a year ago)." Of course it's important to note that capacity doesn't equal generation. Coal still generates more electricity than renewables. But, the trends indicate it's just a matter of time before that picture changes as well. But it is natural gas that is still the king of generation. Although renewable capacity additions are forecast to be well ahead of natural gas additions through 2022, it is likely that natural gas will continue to be the top source of U.S. power for quite some time. The EIU indicates that natural gas now represents 44.44% of total installed capacity. Because of the higher capacity factors for natural gas-fired generation, Energy Information Administration data show that natural gas provided 36% of U.S. power over the past 12 months, well ahead of coal's 27%. Further, the share for natural gas has grown in recent years, while that of coal continues to decline. But given the current trends, it won't be long before renewables supply the largest share of U.S. power.

Renewable Energy Is Now The Cheapest Option - Even Without Subsidies
2019-06-15, Forbes Magazine
Posted: 2019-06-28 01:53:06
https://www.forbes.com/sites/jamesellsmoor/2019/06/15/renewable-energy-is-now...

According to a new report by the International Renewable Energy Agency (IRENA), unsubsidized renewable energy is now most frequently the cheapest source of energy generation. The report finds that the cost of installation and maintenance of renewables, which was an important stumbling block to mass adoption, continues on a downward trajectory. These new statistics demonstrate that using renewable energy is increasingly cost-effective compared to other sources, even when renewables must compete with the heavily-subsidized fossil fuel industry. These lower costs are expected to propel the mass adoption of renewables even further. Among other findings the IRENA report highlights that: Onshore wind and solar PV [photovoltaic] power are now, frequently, less expensive than any fossil-fuel option, without financial assistance. New solar and wind installations will increasingly undercut even the operating-only costs of existing coal-fired plants. Cost forecasts for solar PV and onshore wind continue to be revised as new data emerges, with renewables consistently beating earlier expectations. Further data from REN21's Renewable Global Status Report show that over one fifth of global electrical power production is now generated from renewables. Promising signs in the IRENA report show that ... an increasing number of corporates are entering the renewable energy industry ... meanwhile more than 10 million people are now employed in the global renewable energy industry.

https://www.forbes.com/sites/johnparnell/2019/04/03/one-third-of-worlds-power...

One-third of the world's installed electricity generation capacity is from renewable sources, according to the latest industry statistics. The data compiled by the International Renewable Energy Agency (IRENA) shows that two-thirds of the power capacity added around the world in 2018 was from renewables. Wind and solar accounted for 84% of that total. 2018 was characterized by a spate of solar and wind pricing breakthroughs. Falling interest rates for investors, ongoing technology improvements and regulatory frameworks that encourage competition among would-be developers have all played a part. The geographical distribution of the new plants includes developing and developed economies but it is the former leading the way. The three fastest growing regions were Oceania, Asia and Africa. Asia also became the first terrawatt region, just, with IRENAs figures putting installed renewable capacity at 1,024GW. More than two-thirds of that is in China. Offshore wind capacity has doubled since 2015 but only represented around 4.4GW of the 171GW of renewable power plant deployed in 2018. The concentration of offshore wind remains firmly in Europe (~80%). Solar was the runaway leader of the pack adding 94GW in 2018 to 49GW of wind, on- and offshore. Half of the worlds total installed capacity is currently hydropower but China was the only nation to make substantial hydro additions last year. Bioenergy [added] 6GW.

Battery Powers Latest Plunge in Costs Threatens Coal, Gas

https://about.bnef.com/blog/battery-powers-latest-plunge-costs-threatens-coal...

Two technologies that were immature and expensive only a few years ago but are now at the center of the unfolding low-carbon energy transition have seen spectacular gains in cost-competitiveness in the last year. The latest analysis by research company BloombergNEF (BNEF) shows that the benchmark levelized cost of electricity, or LCOE, for lithium-ion batteries has fallen 35% to $187 per megawatt-hour since the first half of 2018. Meanwhile, the benchmark LCOE for offshore wind has tumbled by 24%. Onshore wind and photovoltaic solar have also gotten cheaper, their respective benchmark LCOE reaching $50 and $57 per megawatt-hour for projects starting construction in early 2019, down 10% and 18% on the equivalent figures of a year ago. Elena Giannakopoulou, head of energy economics at BNEF, commented: Looking back over this decade, there have been staggering improvements in the cost-competitiveness of these low-carbon options, thanks to technology innovation, economies of scale, stiff price competition and manufacturing experience. The most striking finding in this LCOE Update, for the first-half of 2019, is on the cost improvements in lithium-ion batteries. These are opening up new opportunities for them to balance a renewables-heavy generation mix. Batteries co-located with solar or wind projects are starting to compete, in many markets and without subsidy, with coal- and gas-fired generation for the provision of dispatchable power that can be delivered whenever the grid needs it.

Norway's $1tn wealth fund to divest from oil and gas exploration
2019-03-08, The Guardian (One of the UK's leading newspapers)
Posted: 2019-03-25 03:48:01
https://www.theguardian.com/world/2019/mar/08/norways-1tn-wealth-fund-to-dive...

The worlds largest sovereign wealth fund, which manages $1tn (770bn) of Norways assets, is to dump investments in firms that explore for oil and gas, but will still hold stakes in firms such as BP and Shell that have renewable energy divisions. The Government Pension Fund Global (GPFG), whose assets exceed those of rival sovereign wealth funds ... said it would phase out oil exploration from its investment universe. The objective is to reduce the vulnerability of our common wealth to a permanent oil price decline, said Norways finance minister, Siv Jensen. Hence, it is more accurate to sell companies which explore and produce oil and gas, rather than selling a broadly diversified energy sector. Greenpeace UKs oil campaigner, Charlie Kronick, said: This partial divestment from oil and gas [sends] a clear signal that companies betting on the expansion of their oil and gas businesses present an unacceptable risk, not only to the climate but also to investors. While BP and Shell are excluded from the current divestment proposal, they must now recognise that if they continue to spend billions chasing new fossil fuels, they are doomed. Tom Sanzillo, director of finance for the Institute for Energy Economics and Financial Analysis, said: These are very important statements from a big fund. Theyre doing it because fossil fuel stocks are not producing the value that they have historically. He said GPFGs investment strategy also underscores that the fracking business model is unsustainable.

Norway sees boom in electric cars, fueled by the government

A silent revolution has transformed driving in Norway. Some 30 percent of all new cars sport plug-in cables rather than gasoline tanks, compared with 2 percent across Europe overall and 1-2 percent in the U.S. As countries around the world including China, the worlds biggest auto market try to encourage more people to buy electric cars to fight climate change, Norways success has one key driver: the government. It offered big subsidies and perks that it is now due to phase out, but only so long as electric cars remain attractive to buy compared with traditional ones. It should always be cheaper to have a zero emissions car than a regular car, says Climate and Environment Minister Ola Elvestuen, who helped push through a commitment to have only sell zero-emissions cars sold in Norway by 2025. To help sales, the Norwegian government waived hefty vehicle import duties and registration and sales taxes. Owners dont have to pay road tolls, and get free use of ferries and bus lanes in congested city centers. These perks, which are costing the government almost $1 billion this year, are being phased out in 2021, though any road tolls and fees would be limited to half of what gasoline car owners must pay. Gradually, subsidies for electric cars will be replaced by higher taxes on traditional cars. Some 36 percent of all new cars sold are SUVs, which provide safety in the countrys tough winters. Teslas SUV, the Model X - the motor of choice for well-to-do environmentally-minded Norwegians.

UK renewable energy capacity surpasses fossil fuels for first time
2018-11-06, The Guardian (One of the UK's leading newspapers)
Posted: 2018-11-19 22:27:57
https://www.theguardian.com/environment/2018/nov/06/uk-renewable-energy-capac...

The capacity of renewable energy has overtaken that of fossil fuels in the UK for the first time, in a milestone that experts said would have been unthinkable a few years ago. In the past five years, the amount of renewable capacity has tripled while fossil fuels has fallen by one-third, as power stations reached the end of their life or became uneconomic. The result is that between July and September, the capacity of wind, solar, biomass and hydropower reached 41.9 gigawatts, exceeding the 41.2GW capacity of coal, gas and oil-fired power plants. Imperial College London, which compiled the figures, said the rate at which renewables had been built in the past few years was greater than the dash for gas in the 1990s. Dr Iain Staffell, who undertook the research, said: Britains power system is slowly but surely walking away from fossil fuels, and this quarter saw a major milestone on the journey. In terms of installed capacity, wind is the biggest source of renewables at more than 20GW, followed by solar spread across nearly 1m rooftops and in fields. Biomass is third. In the past year, coal capacity has fallen by one-quarter, and there are only six coal-fired plants left in the UK. Coal operators have been affected by the UKs carbon tax on electricity generation, as well as competition from gas.

Plunging Emissions Mostly Not Spurred By Natural Gas Nor Renewables, U.S. Government Finds
2018-10-29, Forbes
Posted: 2018-11-05 02:14:37
https://www.forbes.com/sites/jeffmcmahon/2018/10/29/plunging-emissions-mostly...

Carbon-dioxide emissions from electricity generation fell last year to their lowest level since 1987, the U.S. Energy Information Administration reported today, and the strongest driver is neither the shift from coal to natural gas nor the growth of renewables. More than half of the decline in emissions has occurred because of ... a decline in industrial demand for electricity, the EIA reported. "U.S. electricity demand has decreased in 6 of the past 10 years, as industrial demand has declined and residential and commercial demand has remained relatively flat," writes Perry Lindstrom, a senior energy and environmental analyst. Demand for electricity grew by 1.9 percent per year from 1996 to 2005, but has declined since 2005 by -0.1 percent per year, spurred by rapidly decreasing demand in the industrial sector. If that shift had not taken place, Lindstrom concludes, U.S. power sector emissions would have been 654 million metric tons higher last year. That's slightly larger than the decline in emissions from the power sector's shift to using cleaner fuelsnatural gas and renewables. Cleaner fuels are responsible for saving 645 MMmt of emissions. Today's EIA report does not investigate the reason for the decline in industrial demand, but EIA's past analyses of the industrial sector offer a clue. In its 2017 Manufacturing Energy Consumption Survey, EIA pegged the decline in industrial electricity consumption to a national shift away from energy-intensive industries.

Global demand for fossil fuels will peak in 2023, says thinktank
2018-09-11, The Guardian (One of the UK's leading newspapers)

https://www.theguardian.com/business/2018/sep/11/global-energy-demand-fossil-...

Global demand for fossil fuels will peak in 2023, an influential thinktank has predicted. Explosive growth in wind and solar will combine with action on climate change and slowing growth in energy needs to ensure that fossil fuel demand peaks in the 2020s, Carbon Tracker predicted. The projection is much more bullish than estimates by the global energy watchdog and oil and gas companies, which mostly expect demand to peak in the mid-2030s. Coal reached its peak in 2014. The group, which popularised the notion of a carbon bubble where fossil fuel assets lose their value in the switch to a low-carbon economy said the findings spelled disruption for energy firms. The Bank of England governor, Mark Carney, has already warned that markets face a huge hit from the transition. The Carbon Tracker report warned incumbency and size would be no protection, and compared the fate of fossil fuel firms to the horse and cart at the start of the 20th century. Demand for incumbents peaks early, and investors in incumbents lose money early, it said. The first two decades of this century were the innovation period for renewables, the authors said, while the endgame for fossil fuels when renewables overtake them would come from 2050 onwards. Falling wind and solar costs would lead to some emerging countries leapfrogging fossil fuels and opting for renewables to meet most of their growing energy needs, the thinktank said.

This breakthrough in a type of photosynthesis could provide the world with unlimited energy
2018-09-12, MarketWatch

https://www.marketwatch.com/story/this-breakthrough-in-a-type-of-photosynthes...

Imagine a new, potent generation of solar panels capable of producing unlimited amounts of energy, using only sunshine and algae. This could be possible, thanks to a breakthrough made by researchers from the University of Cambridge, documented in a Nature Energy 2018 article. They were able to split water into its components, oxygen and hydrogen, using what is known as semi-artificial photosynthesis. The procedure has ... never been used to generate large amounts of energy due to expensive and toxic catalysts necessary for the reaction. Photosynthesis [is] the process plants use to convert sunlight into energy. Oxygen is a byproduct of photosynthesis when water absorbed by plants is split. Most of the oxygen on Earth is here because of this photochemical reaction. Hydrogen ... is also produced this way. Now, by combining algae and man-made components, researchers have been able to bypass both natural inefficiency and the use of toxic reactants. This was achieved by enabling a dormant process in algae that uses a special enzyme (hydrogenase) to reduce water into hydrogen and oxygen. Katarzyna Sokol, a researcher on the project ... explains: "Hydrogenase is an enzyme present in algae that is capable of reducing protons into hydrogen. During evolution, this process has been deactivated because it wasnt necessary for survival, but we successfully managed to bypass the inactivity to [split] water into hydrogen and oxygen."

Supersized solar farms are sprouting around the world (and maybe in space, too)

https://www.nbcnews.com/mach/science/supersized-solar-farms-are-sprouting-aro...

Utilities around the world are supersizing their solar farms. Nowhere is that more apparent than in southern Egypt, where what will be the worlds largest solar farm a vast collection of more than 5 million photovoltaic panels is now taking shape. When its completed next year, the $4 billion Benban solar park near Aswan will cover an area 10 times bigger than New Yorks Central Park and generate up to 1.8 gigawatts of electricity. But Benban probably wont hold on to its title for long. China is planning to build a two-gigawatt solar farm in the northwestern province of Ningxia, and the state of Gujarat in western India recently gave the go-ahead for a five-gigawatt facility. Japan is even talking about putting a large-scale solar farm in space. There are huge savings for larger projects, says Benjamin Attia, a solar analyst. A 2017 report from the U.S. National Renewable Energy Laboratory found that the cost of photovoltaic systems shrank by a factor of five from 2010 to 2017. Even the punitive tariffs on Chinese solar panels enacted earlier this year by the Trump administration are unlikely to slow the spread of large-scale solar, which in the U.S. is already cheaper and much cleaner than coal. Governments have wised up, says Attia. They just want the cheapest, fastest way to add new electricity supplies. For nuclear, procurement can take a decade. For gas, its up to four years. If youre talking solar and things go smoothly, you can build a reasonably large project in 18 months.

A floating tidal stream turbine off the coast of Orkney has produced more green energy in a year than Scotlands entire wave and tidal sector produced in the 12 years before it came online. In 12 months of full-time operation, the SR2000 turbine supplied the equivalent annual power demand of about 830 households. It produced 3GWh of renewable electricity during its first year of testing. Over the 12 years before its launch ... wave and tidal energies across Scotland had collectively produced 2.983GWh. Andrew Scott, chief executive officer of developers Scotrenewables Tidal Power, said: The SR2000s phenomenal performance has set a new benchmark for the tidal industry. Its first year of testing has delivered a performance level approaching that of widely deployed mature renewable technologies. He added: The ability to easily access the SR2000 for routine maintenance has been a significant factor in our ability to generate electricity at such levels over the past 12 months, including over winter. The team ... said their success combined with Meygens generation of more than 8GWh over the past year from four tidal turbines deployed in the Pentland Firth is evidence that tidal power generation could be rolled out more widely.

Organic solar cells set 'remarkable' energy record

Chinese researchers have taken what they say is a major step forward for the development of a new generation of solar cells. Manufacturers have long used silicon to make solar panels because the material was the most efficient at converting sunlight into electricity. But organic photovoltaics, made from carbon and plastic, promise a cheaper way of generating electricity. This new study shows that organics can now be just as efficient as silicon. Organic photovoltaics (OPV) can be made of compounds that are dissolved in ink so they can be printed on thin rolls of plastic, they can bend or curve around structures or even be incorporated into clothing. Commercial solar photovoltaics usually covert 15-22% of sunlight, with a world record for a silicon cell of 27.3% reached in this summer in the UK. Organics have long lingered at around half this rate. In April researchers were able to reach 15% in tests. Now this new study pushes that beyond 17% with the authors saying that up to 25% is possible. This is important because according to estimates, with a 15% efficiency and a 20 year lifetime, organic solar cells could produce electricity at a cost of less than 7 cents per kilowatt-hour. In 2017, the average cost of electricity in the US was 10.5 cents per kilowatt-hour. Flexible, printed solar cells offer a wide range of possibilities. They can work indoors and they can be made semi-transparent, so they could be incorporated into windows and generate power during daylight.
