|Different Sources of Renewable Energy
Currently we rely heavily on fossil fuels mainly, coal, oil and natural gas for energy. Fossil fuels are not sources of renewable energy due to the fact that there is not an infinite source of these fuels. In time fossil fuels will disappear and become increasingly more expensive and damage the environment further. Climate change is already happening and as much as we cannot reverse the damage, we can stop it. In contrast to fossil fuels we have many types of renewable energy at our fingertips. These sources are constant and will never run out, making them reliable sources of renewable energy.
Majority of our renewable energy comes from the sun. Sunlight is the source for solar energy and can be used to heat homes, water and being the main source to generate solar electricity. Hot water heating systems and solar cooling can be used in industries beyond the everyday household.
The suns heat drives the winds, a source of renewable energy that is captured with wind turbines. Together the wind and the sun cause evaporation. Once the vapor turns into water, or rain and snow, it flows down into rivers and seas. This power can be captured through the use of hydroelectric power. This is another reliable source of renewable energy that is on our doorstep.
As we all know the partnership of rain and sunlight causes plants to grow. This organic matter that makes the plant is known as biomass that can also be used to generate electricity as well as transport fuels or chemicals. The use of biomass as a renewable energy source is called bioenergy.
Hydrogen is another compound that can be found in organic mass and water. The most abundant element on earth currently is hydrogen. However, it does not occur naturally as a gas. Hydrogen is often combined with other elements, mostly known as oxygen, which combined with hydrogen makes water. Once we separate hydrogen from other elements it can be burned as fuel or converted into electricity. Hydrogen is a major component to the different types of renewable energy.
As you can see, not all renewable energy sources come from the sun. Geothermal energy taps into the earth’s internal heat for a vast variety of renewable energy uses. One of the renewable energy resources that geothermal energy can offer is electric power production, and the cooling and heating of buildings.
Our oceans offer a great source for renewable energy. The oceans tides come from the gravitational pull of the moon and sun. This is why when there is a full moon the tides are very high. Ocean energy comes from a variety of sources. Tidal energy is becoming a common source of renewable energy. The oceans waves offer an energy that is driven by the tides and the winds. The sun warms the surface of the ocean and creates a temperature difference that can also be used as a renewable energy source. All forms of ocean energy can be produced into renewable electrical energy.
