- What is sustainable energy ?
- The difference between renewable and sustainable energy
It does not emit greenhouse gases, but is considered a conventional source because It has been used for a long time. The energy is produced by the water power.
Oil is one of the most common and conventional sources of fossil-fuel energy production. It keeps the nation's transportation systems moving -- through the production of gasoline, diesel and aviation fuel -- and the cost effectiveness of these fuels is a critical element of small-business operations.
Coal is a biofuel that serves as an effective heat-energy source, and it is used in electricity generation and as fuel for power plants.
he movement of the atmosphere is driven by differences of temperature at the Earth's surface due to varying temperatures of the Earth's surface when lit by sunlight. Wind energy can be used to pump water or generate electricity, but requires extensive areal coverage to produce significant amounts of energy.
Energy left over from the original accretion of the planet and augmented by heat from radioactive decay seeps out slowly everywhere, everyday. In certain areas the geothermal gradient (increase in temperature with depth) is high enough to exploit to generate electricity.
Solar energy is one the most resourceful sources of energy for the future. Solar energy is presently being used on a smaller scale in furnaces for homes and to heat up swimming pools. On a larger scale use, solar energy could be used to run cars, power plants, and space ships.
