In a hotly contested vote today, Europe’s Parliament voted to cap the amount of conventional or “first-generation” biofuels (those derived from food crops) that can be used in the EU’s transport sector.
Solar thermal water heating is a temperamental thing. Water weighs a lot, it expands when it freezes, and it can cause scaling damage to pipes when it boils. Solar thermal systems are wonderfully efficient, and some systems work just fine for decades, but even these need regular inspection. When a solar thermal system fails, however, it sets about destroying itself, and it has been clear for some time that solar thermal water heating is not the way of the future except for very low-end heat usage, like swimming pools.
Two great opportunities to learn more about solar are about to occur: The National Solar Tour and The Solar Decathlon. The former is an annual event across the U.S. and the latter is a biennial event. Both allow people across the U.S. to get an in-person view of solar and how it works. The National Solar Tour is, as it name implies, a national eve
A US$600,000 grant from the National Science Foundation will allow the University of Minnesota's St. Anthony Falls Laboratory (SAFL) to launch a new collaborative project to advance research, innovation and training in marine and hydrokinetic (MHK) technology.
Chile has become one of the planet's most promising solar markets, leading a wave of regions that will begin achieving grid parity, where solar is at equal cost or cheaper than traditional energy sources, in the near future. High electricity prices ($0.15-0.25/kWh), high irradiation, and rising energy demand all play in Chile's favor, but connection and policy hurdles remain if the country wants to really start tapping into that resource.
The symbiotic match between the solar and energy storage sectors shows significant market promise and could see the sector yielding a US $2.8 billion market over the next five years,
Development banks worldwide lent a record $108.9 billion to renewable energy and energy-efficient technology last year as they scale back investment in coal-fired power plants, Bloomberg New Energy Finance said.
Community renewable energy has significant political and economic benefits, but is often hindered by five major barriers. Read on for a summary of the five barriers, watch them in a 17-minute presentation, or check out the illustrated slideshow below. Barrier one is tradition. Utilities are simply used to operating a grid in a 20th century model,
As kids we were told “don’t play with matches.” The reasoning was simple. But as adults, we ignore this warning and play with fire to heat our homes and office buildings and our laws and policies encourage it. It doesn’t have to be that way. We need to create paths to safer, cleaner and more efficient energy sources to satisfy the “thermal loads” of buildings and geothermal heat pumps (GHPs) are the answer.
Generaytor's NFL goes solar infographic celebrates the 2013 season’s kickoff by showcasing five solar-powered stadiums. Which NFL teams are green on game day? There's more to it than just the uniforms and Generaytor set out to investigate. East coast teams have an early lead in solar production, but the new San Francisco stadium will be solar-pow
A plan for a 50-MW capacity pumped storage facility capable of generating up to 500 MWh of energy has been approved by the local council, the developer has announced. The facility will be built in the Glyn Rhonwy cluster of abandoned slate quarries near Llanberis in north Wales.
It’s amazing what a couple of lines of legislation can do. California law states that utilities would have to stop offering net metering at the end of 2014. With more residents and solar installed than anywhere else in the U.S., such an abrupt end could spell disaster for the residential solar market in the state. In light of that legislation, AB
Australia’s standards body, Standards Australia, has published the world’s first solar cooling standard.
Carnige Melon University’s Climate and Energy Decision Making Center’s recent study, “Regional variations in the health, environmental, and climate benefits of wind and solar generation,” is a testimony to the difficulty of cost justifying renewable energy development.
Back when silicon prices were north of $400/kg, finding ways to use less material was seen as a keen opportunity, from different formfactors to thinner wafers. One group of efforts centered on "upgraded metallurgical-grade" (UMG) silicon, which was essentially a grade of silicon slightly less than the ultrapurity required by the electronics industry. Those efforts broadly lost their appeal, though, once silicon prices plunged to $20/kg and below, though prices have started showing signs of rising slightly.
An aging infrastructure and increasing demand for energy makes technology more important than ever in meeting and sustaining the power needs of the world. In its 2012 World Energy Outlook, the International Energy Agency said global energy dependency will grow by more than 30 percent between now and 2035. As the shift to more renewable sources catches on, questions are raised about how to make grids more flexible and better able to accommodate intermittent renewable generation. Alstom Grid believes high voltage, direct current (HVDC) technologies are part of the answer.
Only five solar-power vendors remain in a space built for 170 at a sprawling complex of offices stacked three stories high outside Xinyu city in China’s southeast. Locked doors and empty offices are what’s left of the government’s audacious plan to dominate the global solar industry. What happened in Xinyu is being replicated across China, which used subsidies and $47.5 billion of credit to wrest supremacy from Germany, Japan and the U.S., saddling an industry with losses for at least two years.
The wind energy industry has traditionally relied on hub-height towers designed for the communications industry. Built-up lattice towers required climbers to install equipment precisely at 60, 80 or even 100 meters in the air. In recent years, the wind measurement landscape has changed rapidly and the result is more accurate wind energy resource and power performance verification campaigns to reduce the financial risk associated with wind farms and boost accuracy in determining energy output from wind farms.
Fewer of China’s wind turbines are idle after investments in new wind farms slowed and developments shifted to areas with better grid access, aiding operators such as China Longyuan Power Group Corp.
Efforts to roll back rules that nurtured the corn-based ethanol industry threaten to stunt other promising biofuels, according to a developer working on one of the nation’s first commercial plants that won’t use the grain.
