new energy efficient glass

China’s building sector accounts for more than 25 percent of China’s energy use. Improving the efficiency of its buildings, new and old, is a key part of China’s strategy to reduce energy demand.[read more]

reducing wireless energy demand

The GreenTouch consortium outlines energy efficiency measures that could reduce the net energy consumption of global data and communications networks up to 90% by 2020, compared to 2010 levels.[read more]

The idea of an “artificial leaf” sounds simple enough: Take a small, cheap, light-collecting device the size of a typical leaf, dunk it in a quart of water, and use solar energy to generate enough hydrogen gas for powering a small fuel cell.[read more]

hydropower in China

Reuters reports that China’s environmental ministry has okayed the construction of a new hydroelectric dam on the Dadu River in the Sichuan province, which when completed will be the country’s largest.[read more]

military solar energy

The Army, Navy and Air Force are using more than 130 megawatts of solar energy, with intentions toward 3 gigawatts of solar capacity by 2025 as part of a much bigger Department of Defense commitment.[read more]

Belo Monte controversies continue

The latest installment of the saga has been the expulsion of journalists from the site where they would cover the latest protest by indigenous activists who have brought the building of the dam to a halt.[read more]

North American Young Generations in Nuclear group

It will take me several days to digest all of the things I learned and heard at the Nuclear Energy Assembly, both from the podium and in the valuable “hallway conversations.”[read more]

Even if there is enough lithium to displace the 1 billion internal combustion engine cars that now pollute the earth with electric cars, it is the electronic waste problem that should dominate the question.[read more]

fat for energy?

Oil and fat accumulating under the streets of London is apparently causing a bit of an issue. However, the city is going to burn these fatbergs in order to create electricity — about 130 GWh of electricity per year.[read more]

solar vs nuclear energy costs

Germany’s solar program will generate electricity at quadruple the cost of one of the most expensive nuclear power plants in the world, raising serious questions about a renewable energy strategy widely heralded as a global model.[read more]

Nuclear energy costs

 

On Saturday, the Tampa Bay Times published a lengthy piece that argues the two reactor installation proposed for Levy County, Florida is a more expensive option than a natural gas power plant.[read more]
