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.
The sun is directly and indirectly responsible for four of our renewable energy options, but the most obvious is solar energy. Solar energy produces electricity from the sun and is used in business, industry, and the home. It can power our lights, heat our water, cool our homes, and produce the electricity we need to run our appliances and gadgets. While just about any area of the world can benefit from solar energy, it is most useful in those parts of the world with high sun exposure for the majority of the year.
Wind energy, which comes from the sun’s heating effect on the air, can also be used for providing electricity. Energy from the wind is collected by wind turbines and then applied to agriculture, industry, and home uses. It is the reaction of sun and wind that causes water evaporation, which leads to precipitation of snow and rain. The water from rain and melting snow flows into our earth’s streams and rivers, where the energy can be turned into hydroelectric power.
The sun and water nourish the plants, and plants become biomass. Organic matter provides fuels, produces electricity, and provides essential chemicals to power our world. The energy from biomass is called bioenergy. Renewable bioenergy comes from life, then supports life, which continues to cycle in the circle of organic life.
Renewable energy is not always connected to the sun. We can use energy that is created from the earth’s heat to heat and cool our homes and other buildings. This source is geothermal energy. Geothermal energy is also a reliable source for the production of electricity.
Then, there are ocean energies. The majority of our beautiful planet is covered by the world’s oceans, and these oceans contain more than one way of providing renewable energy. Gravity causes tides, the winds and tidal pulls create waves. This is referred to as wave energy. We can also capture energy from the sun-heated parts of the ocean.
The discovery of coal and oil as sources of energy helped to create the industrial and technical world we live in, but in order to continue to power a technologically-evolving earth, we must do further research into all different types of renewable energy. Oil and coal will not renew — at least not fast enough to keep up with a growing world that depends on electric power. Of all the choices we have, we continue to use non-renewable fuels that poison our water and pollute our air. We strip our forests fast and fail to plant with equal vigor. Renewable energy is our hope for the future of the planet.
Renewable energy can provide job security and put money back into local economies. This is because careers in renewable energy are built around maintaining an endless resource, rather than producing from energies that will run out. Money spent on renewable energy sources and investments in earth-friendly energy puts money into the local economy. Rather than boosting the economies of people across the world, we can lend a hand to our local economies.
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 dumpsterrentallongbeach.org we are invested in eco friendly campaigns including recycling and sustainable energy if possible.
