The U.S. Army is driving a huge new market for renewable energy, dangling up to $7 billion to purchase power sourced from solar, wind, biomass, geothermal and other alternative-energy technologies.
Yes, I know all the reasons why air conditioning is less than environmentally-friendly.
Inconsistency of supply is one of the biggest drawbacks of renewables such as wind and solar.
Put simply: the wind doesn't blow all day, and the sun doesn't shine at night.
According to researchers at the US Naval Research Laboratory (NRL), one of the Marine Corps’ most significant challenges is finding a way to provide reliable electricity to soldiers in forward operating bases.
Imagine the most luxurious floating resort imaginable, a full 1,184 square feet of teak deck and passenger accommodations.
When someone mentions switching to solar power, we often envision photovoltaic panels fixed onto the roof of a house or lined up in a field.
Everyone knows it: to take full advantage of solar and wind resources, we need to develop better ways to store the power they produce.
New York City is a big city, and it's been big for a long time - long enough to create, and close, a huge landfill, known as Fresh Kills.
Anyone who knew Miles C. Barr as a kid no doubt realized he'd go far one day.
Last Fourth of July weekend, the U.S. Army‘s Tank Automotive Research, Development and Engineering Center (TARDEC) in Warren, Michigan experienced a power outage that halted operations of its laboratories.
So, increasingly, we've got this whole renewable energy thing going on. But integrating all that new solar and wind power into the power grid remains a challenge.
Most people understand that once solar panels are paid off, the energy they provide is free. But what about on a national level?
The days of constructing energy-hogging buildings could soon be something considered so 2010.
Are big solar and wind – like oil and gas – ready to compete to use resources on federal lands?
The US Department of Defense (DoD) is currently engaged in a "hard push" to significantly reduce dependence on fossil fuels in an effort to shrink risks on the battlefield.
California regulators have approved five power purchase agreements that could boost the state's renewable energy capacity by 1,088 megawatts (MW) and produce 2,927 gigawatt-hours (GWh) of energy.
There is a moment in Bill Jaeger's latest biofuels paper when his scholarly posture crumples a bit and he seems to want to shout loud enough for policymakers in Washington, D.C., to hear him all the way from Corvallis, Oregon.
Theoretically, the maximum efficiency of today's silicon solar cell is approximately 31 percent, because much of the solar energy that hits the cell is lost as heat.
Progressives have never been very good about admitting - let alone claiming - victory.
It might have been a biomass cogeneration plant in Brazil, or a wind farm in Mexico.
Or perhaps that solar thermal plant in Morocco.
