Renewable Energy is the future. Because Coal, oil and gas are fossil fuels they are not suitable to supply a growing population and will not be accessible in the future.
What is a Renewable Energy source?
Renewable energy is energy that comes from natural resources such as solar, wind, tidal and geothermal. Due to there ultimate source they are also known as Infinite Sources of Energy.
Sources of Energy:
- Solar
- Wind
- Tidal
- Geothermal
Solar
This is the conversion of sunlight into electricity. This is done by photovoltaics (PV) or indirectly using concentrated solar power (CSP). The first commercial solar power station was first built and operational in the Mojave Desert in California US. It generated 354 MW SEGS CSP. More ecological and modern homes are now being fixed with compact solar panels.
Wind
Ireland is a perfect nation to harness this energy. Due to our abundant wind source it is important that we learn how to avail of this energy. There is unfortunately a down turn to wind energy. Turbines would require a large amount of space to build large wind farms. The largest turbine can provide enough energy for 475 homes on full capacity. It is difficult to do this for large cities.
Tidal
Tidal Power or Hydropower is the conversion or energy of tides into electricity.As Ireland lies on the Atlantic ocean where waves are strong it is possible to harness huge amounts of energy. Turbines in the water generate energy while being moved by currents or tides. Unfortunately Government funding is lacking in the funding and development of thus energy.
Geothermal
This is the use of heat energy below the surface of the earth. Estimations believe that this energy can harness up to 2000 GW. The Earth's heat content is 1000 joules. It is believed that 75% of the earth's heat may be used to generate power.
