On 13 September, the U.S. Department of Energy (DOE) released a report suggesting that, in theory, over 300 former and present coal power plants could be converted to nuclear. Such a conversion has never been done, but the report is another sign that the idea is gaining momentum—if with the slow steps of a baby needing …

A closer look at California's longer energy history across the 19th and 20th century, though, gives us a somewhat different picture. Beginning in the late 1800s, the discovery of enormous natural gas and oil reservoirs in the Central Valley eventually gave rise to the state's booming fossil fuel economy, turning California into a national suppler of crude oil …

Coal fired power plants are one of the main sources of electricity generation in the world. They use coal as a fuel to heat water and create steam, which then spins a turbine to produce electricity. However, coal fired power plants also have many environmental and health impacts, such as greenhouse gas emissions, air pollution, and coal ash disposal. …

The current major source of energy/fuel is fossil fuel, which, for all practical purposes can be considered to be nonrenewable. Fossil fuels are all petroleum derivatives and the use of these fossil fuels leads to the generation of greenhouse gases such as CO 2, CH 4, N 2 O. The transportation sector is responsible for the highest rate of growth in …

Supercritical water, in turn, can carry some 5-10 times more energy than regular hot water, making it an extremely efficient energy source. "When you think about taking that energy density and dividing it by the cost to develop a [geothermal] field, you see a step change in economics to geothermal," Bonebrake said.

Measuring energy in food. Food calories are a measure of energy in food. One food calorie is equal to 1,000 calories, or 1 kilocalorie. For example, the energy in a 300 food-calorie ice cream cone is about the same as the amount of electricity required to light a 100-watt incandescent light bulb for 3.5 hours.
