With the growing concerns about global warming, rising oil and gas prices, and the increase in pollution in our air, water, and soil, governments from all over the world are now searching for ways to implement more renewable energy sources. The supply of fossil fuels is finite, and eventually the world’s non-renewable energy sources will be depleted so it has become essential to use green energy to create a sustainable future.
The following are a number of innovative green energy solutions:
Hydroelectric Power: Water is an environmentally friendly source of energy and is the most widely-used renewable source of energy. This green energy is generated by driving turbines from the force of falling water. How much energy is produced will depend on the available water flow and the height that the water falls. The fast flowing water powers the water wheels that drive mechanical processes. This is transformed into mechanical energy. The turbine’s rotation spins electromagnets which generate current in stationary coils of wire. The current is then sent through a transformer where the voltage is amplified for long distance conduction over power lines. Water energy dispenses about 60 times less than a coal plant and 30 times less greenhouse gas than gas power plants.
Wind Power: Wind power is generated using the wind. Wind turbines are used to generate the energy. The wind blows the propeller causing it to turn and this causes the turning of a generator to produce electricity. They can be installed wherever there is a good supply of strong wind. The more wind towers and the larger the propellers, the more wind, and the more electricity is produced.
Solar Power: Solar power is the production of electricity from the sunlight. This type of power can be used for heat and electricity. The solar panels harness the sun’s energy without moving parts, pollution, radiation, or noise. One method of using solar energy involves using mirrors to reflect and focus the sun’s rays, providing heat, which helps power a generator. Another method is photovoltaic panels. Solar panels are installed on the roofs of buildings and homes. The panels run generators which provide the electricity.
Geothermal Energy: This energy comes from the heat within the earth. One will capture this energy source by drilling a hole into the ground to acquire the heat. The heat that is harnessed is used to heat water and create steam to power the generators to create the electricity.
Biomass Energy: This is energy from trees and plants. These plants are harvested and their energy is converted to ethanol which can be burned directly by power plants or vehicles to generate power. Ethanol can be added to gasoline that goes in vehicles. However, recently bio-fuels have been found to be a source of greenhouse gases.
The use of renewable energy sources are increasing throughout the world. Solar and wind energies are two green energies that have made significant growth in their use. By using green energy, we are helping to ensure a healthy future and planet for our children.
