Oil and hydroelectric follow at around 25 percent each, followed by natural gas at 9 percent and coal at 2 percent. [3] Excluding Chernobyl and the Shimantan Dam, the three other most expensive accidents involved the Exxon Valdez oil spill (Alaska), The Prestige oil spill (Spain), and the Three Mile Island nuclear accident (Pennsylvania).

Natural gas is much cleaner than oil in terms of emissions. [79] However natural gas has its limitation in terms of mass production. For example, in order to switch from crude oil to natural gas there are technical and network changes that need to occur before the implementation can be complete.
All thermal power plants (coal, natural gas, nuclear, geothermal, and biomass) use water as a cooling fluid to drive the thermodynamic cycles that allow electricity to be extracted from heat energy. Solar uses water for cleaning equipment, while hydroelectricity has water usage from evaporation from the reservoirs.
Analysts believe that China’s 15 percent tariff on U.S. liquefied natural gas — the tariff went into effect Monday — will undermine America’s ability to sell energy to the world. In fact ...
The three fossil fuel types are coal, petroleum and natural gas. It was estimated by the Energy Information Administration that in 2006 primary sources of energy consisted of petroleum 36.8%, coal 26.6%, natural gas 22.9%, amounting to an 86% share for fossil fuels in primary energy production in the world.

Environmental Protection Agency illustration of the water cycle of hydraulic fracturing. Fracking in the United States began in 1949. [1] According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.
Here are the actual risks, according to an atmospheric chemist.
A 16-part assessment of methane leakage from natural gas production initiated by the Environmental Defense Fund [39] found that fugitive emissions in key stages of the natural gas production process are significantly higher than estimates in the EPA's national emission inventory, with a leakage rate of 2.3 percent of overall natural gas output ...
