The typical energy resources currently in use include non-renewable sources that will not last forever. In fact, we have already used up a large percentage of the earth’s non-replenishing resources. This is having a profound destructive effect on not only our economy, but the environment. However, recent research has increased the interest in lower-cost renewable energy resources that do not harm the earth’s environment. These resources include solar, wind, organic matter, geothermal, and water.
Most of our renewable energy options come from the sun. Solar energy, or energy that is produced via the sun’s rays, is used for residential, industrial, and commercial purposes. Solar energy is used for heating water, cooling the air, and providing electricity to run lights and machines. While energy from solar resources is most widely used in areas with a great degree of exposure to the sun, it has applications in all parts of the world.
Driven by the heat of the sun, the wind’s energy is captured by windmills, or wind turbines, and distributed for agricultural, industrial, and residential purposes. Sun and wind cause the evaporation of water. This produces precipitation, which flows into the world’s rivers. We can capture its energy through the use of hydroelectric power plants.
Another type of renewable energy is biomass. Energy from biomass comes from organic matter, which grows and develops from sun and water. The bioenergy we receive from biomass makes fuels, chemicals, and electricity we can use to survive and assist all life on earth. Bioenergy, or life energy, is a resource that continues to renew year after year.
All renewable energies do not come from solar resources. The energy we can get from heat inside the earth is called geothermal energy. Geothermal energy can provide the energy we need for electricity, as well as heating and cooling.
Our earth is made up of seven continents, which are surrounded by oceans, which provide two important sources of energy. Tides and wind create waves. Tidal energy is renewable, and wave energy is consistently renewable with wind, water, and tides. That is not all there is! The difference in temperature of ocean water from the icy cold depths to the shallower, warmer water that has been heated by the sun is also a source of energy.
Our large-scale consumption of non-renewing energy is damaging the environment we live in. We can make a dramatic change for the better by using sources that will not run out, but continue to renew and sustain the world. The destruction of our rainforests is due in large part to energy consumption. Oil drilling and coal mining strips the land and leaves toxins in our air and water. The side effect of using these fuels is damage to all living things.
Energy resources that renew are good for the economy. When people and corporations invest in renewable energy, most of the profits go back into the helping the local economy, rather than profiting commercial operations and industries on the other side of the globe. Renewable energy jobs are more secure than jobs in oil or coal. Renewable energy never depletes, but it must be harnessed, equipment will always be necessary, and although it does do most of the renewing on its own, it must be supervised.
The hard truth of the matter is that non-renewable energy sources will eventually run out. If we do not switch over to the renewable energy sources we will leave an injured and scarred world for our descendants. Make no mistake, there is such a thing as too late.
At dumpsterrentalbuffalo.org our company is focused on green campaigns such as recycling and also renewable energy sources whenever possible.
