International crude oil and liquefied fuels movements depend on reliable transport through key chokepoints. In 2011, total world crude oil and liquefied fuels consumption amounted to approximately 88 million barrels per day […]
Electric grid operators monitoring drought conditions
Prolonged drought can affect power plants that rely on large volumes of fresh water for a variety of reasons. Though there have been few reported problems this year, lower water levels are […]
SEIA Sheds Light on Tax Treatment of Solar Financing
There has been a lot of dialogue on this site about the future of solar financing and the tax treatment of various solar financing scenarios, and we at the Solar Energy Industries […]
Battery Performance Deficit Disorder
Batteries fail—as certainly as death and taxes. Rechargeable batteries at least offer the possibility of repeating the cycle, so are in this sense more like recurrent taxes than death. But alas, the […]
Drought has significant effect on corn crop condition, projected ethanol production
The U.S. Department of Agriculture (USDA) has reported a significant rise in the proportion of poor and very poor corn crops this summer, due largely to the extreme drought across much of […]
Geothermal Energy’s Trouble Competing With Solar
A geothermal power plant can deliver electricity day or night and help California utilities meet the state’s renewable energy mandate. But geothermal energy developers in California are feeling a bit left out […]

Bioethanol or Biodiesel: Europe Hesitates over Indirect Impact of Green Fuel
For years Europe has encouraged motorists to use diesel over petrol in its efforts to cut carbon dioxide emissions. Now, as the focus switches to introducing renewable fuels, it is proving far […]
U.S. Geothermal Energy Potential is Heating Up
Geothermal energy in the United States has the potential to have an installed capacity of 100,000 megawatts (MW) within the next 50 years, according to a report published by an interdisciplinary panel […]
PV System Values: Solar Energy Needs Electrical Storage Now
Dramatic cost reduction in photovoltaics (PV), combined with lower electrical storage costs from batteries for the automotive industry, are creating new business opportunities for grid-tied PV systems that include energy storage. This […]
