    Nuclear energyenergy in the nucleus or core of atoms [1] Nuclear fusion; Nuclear reactor; Nuclear reprocessing; Oil drilling; Oil platform; Oil refinery; Oil shale; Oil well; Osmotic power – or salinity gradient power – is the energy available from the difference in the salt concentration between seawater and river water. OTEC ...

  3. Renewable energy - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy

    As an energy source, biomass can either be used directly via combustion to produce heat, or converted to a more energy-dense biofuel like ethanol. Wood is the most significant biomass energy source as of 2012 [103] and is usually sourced from a trees cleared for silvicultural reasons or fire prevention.

  4. World energy resources - Wikipedia

    en.wikipedia.org/wiki/World_energy_resources

    Renewable energy sources are even larger than the traditional fossil fuels and in theory can easily supply the world's energy needs. 89 PW [32] of solar power falls on the planet's surface. While it is not possible to capture all, or even most, of this energy, capturing less than 0.02% would be enough to meet the current energy needs.

  6. Life-cycle greenhouse gas emissions of energy sources

    en.wikipedia.org/wiki/Life-cycle_greenhouse_gas...

    Although the life cycle assessments of each energy source should attempt to cover the full life cycle of the source from cradle-to-grave, they are generally limited to the construction and operation phase. The most rigorously studied phases are those of material and fuel mining, construction, operation, and waste management.

  7. World energy supply and consumption - Wikipedia

    en.wikipedia.org/wiki/World_energy_supply_and...

    Primary energy sources are transformed by the energy sector to generate energy carriers. Energy resources must be processed in order to make it suitable for final consumption. For example, there may be various impurities in raw coal mined or raw natural gas that was produced from an oil well that may make it unsuitable to be burned in a power ...

  8. Energy mix - Wikipedia

    en.wikipedia.org/wiki/Energy_mix

    The energy mix is a group of different primary energy sources from which secondary energy for direct use - such as electricity - is produced. [1] Energy mix refers to all direct uses of energy, such as transportation and housing, and should not be confused with power generation mix, which refers only to generation of electricity, [ 2 ] as ...

  9. Sustainable energy - Wikipedia

    en.wikipedia.org/wiki/Sustainable_energy

    Renewable energy sources are essential to sustainable energy, as they generally strengthen energy security and emit far fewer greenhouse gases than fossil fuels. [49] Renewable energy projects sometimes raise significant sustainability concerns, such as risks to biodiversity when areas of high ecological value are converted to bioenergy ...
