What is the Cheapest Form of Energy? | AltEnergyMag
Not long ago, coal was the cheapest form of energy. Now, solar and wind plants are half the cost of new coal plants. Cheap renewable energy and low-priced batteries are anticipated to lead to wind and solar producing 50 percent of the world's electricity generation by 2050. Renewable energy sources are beginning to take over the power sector ...

Cost of Wind vs. Fossil Fuels - MEIC
A clean energy economy could double Montana's statewide energy jobs by 2030 while also growing wages. Median wages in wind energy are 34% higher than those in coal mining and are comparable to those in fossil fuel electricity generation. Coal has become uneconomic as other forms of energy have dropped in price.

Coal also provides a stable source of energy (no Arab oil embargoes, no sudden scarcity like you experience with natural gas) and there is a very plentiful supply both in the U.S. and in other foreign countries. Coal is nothing more than ancient wood which has been under pressure for millions of years.

Primary energy sources include petroleum, natural gas, coal, biomass, flowing water, wind, and solar radiation. Those are the fuels that can be mined, reaped, extracted, harvested, or harnessed directly. Secondary energy cannot be harnessed directly from nature; rather, secondary energy is energy that has already been converted.

Our Energy Sources, Natural Gas — The National Academies
Like all fossil fuels, its combustion emits carbon dioxide, but at about half the rate of coal per kilowatt hour of electricity generated. It is also more energy efficient. On average, a typical coal-burning power plant in 2013 was about 33% efficient in converting heat energy into electrical power. A gas-fired plant was about 42% efficient.
