8 clean energy predictions from a decade ago…that were way wrong

From the Fresh Energy blog and a good reminder that most experts have trouble thinking exponentially 윈도우 보안 패치 다운로드.

 

WIND

  • In 2000, the International Energy Agency (IEA) published its World Energy Outlook, predicting that non-hydro renewable energy would comprise 3 percent of global energy by 2020. That benchmark was reached in 2008 다운로드.
  • In 2000, IEA projected that there would be 30 gigawatts of wind power worldwide by 2010, but the estimate was off by a factor of 7. Wind power produced 200 gigawatts in 2010, an investment of approximately $400 billion 다운로드.
  • In 1999, the U.S. Department of Energy estimated that total U.S. wind power capacity could reach 10 gigawatts by 2010. The country reached that amount in 2006 and quadrupled between 2006 and 2010 윈도우 서버 업데이트 다운로드.
  • In 2000, the European Wind Energy Association predicted Europe would have 50 gigawatts of wind by 2010 and boosted that estimate to 75 two years later. Actually, 84 gigawatts of wind power were feeding into the European electric grid by 2012 다운로드.
  • In 2000, IEA estimated that China would have 2 gigwatts of wind power installed by 2010. China reached 45 gigawatts by the end of 2010. The IEA projected that China wind power in 2020 would be 3.7 gigawatts, but most projections now exceed 150 gigawatts, or 40 times more consolas 폰트 다운로드.

SOLAR

  • In 2000, total installed global photovoltaic solar capacity was 1.5 gigawatts, and most of it was off-the-grid, like solar on NASA satellites or on cabins in the mountains or woods 드럼 효과음 다운로드.
  • In 2002, a top industry analyst predicted an additional 1 gigawatt annual market by 2010. The annual market in 2010 was 17 times that at 17 gigawatts 다운로드.
  • In 1996, the World Bank estimated 0.5 gigwatts of solar photovoltaic in China by 2020, but China reached almost double that mark—900 megawatts by 2010 다운로드.

ARPA-E – a new federal agency created to fund research of promising, but unproven, energy technologies

ARPA-E: A Good Beginning for U.S. Energy Innovation

By Bill Gates

Clean energy and innovation are two areas that I’m passionate about, so I’ve been looking forward to investigating some interesting new energy technologies at the ARPA-E Energy Innovation Summit this week 다운로드.

ARPA-E is a new federal agency—the Advanced Research Projects Agency-Energy—created in 2009 to fund research of promising, but unproven, energy technologies 다운로드. It was modeled after DARPA—the Defense Advanced Research Projects Agency—which was established in the late 1950s to accelerate development of U.S 다운로드. satellite technology to keep pace with the Soviet Union. Research at DARPA led to a number of fantastic breakthroughs, including GPS technology and the Internet 레미제라블 무료.

The idea behind ARPA-E is to help the U.S. fast-track development of innovative energy technologies that wouldn’t typically be funded by traditional energy companies 다운로드. If just a fraction of the projects are successful, they could reduce greenhouse gas emissions contributing to climate change, help the U.S. decrease its dependence on foreign oil, , and keep the U.S 샤롯데체 다운로드. competitive in advanced energy technologies.

I’ve been quite impressed with the people running ARPA-E. In less than three years, they have evaluated hundreds of proposals and made $521 million in grants to support 180 projects 다운로드.

Energy Department invests millions to accelerate high-volume solar manufacturing

A $25 million federal grant will speed the construction of a solar manufacturing plant in San Diego, in an effort to boost U.S. competitiveness 새벽기도음악 다운로드.

Semiconductor maker Soitec Solar, recipient of the Department of Energy grant, will pour the funds into equipment at its Rancho Bernando-area plant 다운로드. Production is set to start before the end of the year on concentrated photovoltaic modules that use optical lenses to focus sunlight on tiny, highly efficient solar cells 비커밍제인.

A publicly traded company based in Bernin, France, Soitec entered the concentrated photovoltaics business in 2009 with the purchase of Concentrix Solar, a spinoff of the Fraunhofer Institutes, a network of publicly funded research centers in Germany 3월 모의고사 다운로드.

Soitec received the largest share of $37 million in Energy Department grants designed to accelerate high-volume solar manufacturing over the next two years 다운로드.

More about Soitec’s CPV (concentrated photovoltaic) modules:

Soitec’s CPV modules are built on Concentrix technology 다운로드. They use Fresnel lenses to concentrate sunlight 500 times and focus it onto small, highly efficient multi-junction solar cells. This technology has helped us achieve world-leading AC system efficiency increases of 25% in actual operating conditions 다운로드. This is almost twice as high as the efficiency increases achieved using conventional silicon systems.

America regains the title of ‘fastest supercomputer on the planet’

Every six months, Earth’s biggest supercomputers have a giant race to see which can lay claim to being the world’s fastest high-performance computing cluster 다운로드.

In the latest Top 500 Supercomputer Sites list unveiled Monday morning, a newly assembled cluster built with IBM hardware at the Department of Energy’s Lawrence Livermore National Laboratory (LLNL) takes the top prize 고양이마리오. Its speed? A whopping 16.32 petaflops, or 16 thousand trillion calculations per second. With 96 racks, 98,304 compute nodes, 1.6 million cores, and 1.6 petabytes of memory across 4,500 square feet, the IBM Blue Gene/Q system installed at LLNL overtakes the 10-petaflop, 705,000-core “K computer” in Japan’s RIKEN Advanced Institute for Computational Science 다운로드.

The Japanese computer had been world’s fastest twice in a row. Before that, the top spot was held by a Chinese system. The DOE computer, named “Sequoia,” was delivered to LLNL between January and April 2019년 달력 한글 다운로드. It’s the first US system to be ranked #1 since November 2009.

To get to 16 petaflops, Sequoia ran the Linpack benchmark for 23 hours without a single core failing, LLNL division leader Kim Cupps told Ars Friday in advance of the list’s release 다운로드. The system is capable of hitting more than 20 petaflops—during the tests it ran at 81 percent efficiency.
