How can electricity be generated without coal or water?

Answer 1

-- Burn oil, natural gas, gasoline, kerosene, paraffin, diesel fuel, paper, oily rags,

buffalo dung, dry lemon grass, corn stalks, or wood, in oxygen. Capture the heat

to boil water and spin a steam turbine. Ooops! Water was used.

-- Allow a controlled nuclear fission reaction to proceed slowly in a closed vessel.

Capture the heat to boil water and spin a steam turbine. Ooops! Water was used.

-- Employ several people or water buffalo to pedal stationary bicycles or walk

harnessed in an endless circle, with their respective machinery suitably coupled

to an electric generator. No water is used except that required to keep the

prime movers conscious.

-- Allow the sun to shine onto a panel comprised of photovoltaic cells in series/parallel

configuration. Collect and store free electrical energy.

Answer 2

Electricity can be generated without coal or water using renewable energy sources such as solar, wind, and geothermal power. Solar panels convert sunlight into electricity, wind turbines generate electricity from wind, and geothermal power plants tap into heat from the Earth's core to produce electricity. These clean energy sources have minimal environmental impact compared to coal-fired power plants.
