Most of the energy we produce and use comes from non-sustainable resources. Our energy usage has taken its toll on the world. We can see the environmental and economic damage all around us, and yet we continue to use too little of the renewable energy types of resources we should be using, while using too much of those that cannot be renewed. Research into renewable energy has revealed several different types of which we can take advantage. These types are from the sun, wind, organics, earth, 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.
Everybody knows that it is sun and rain that makes plants grow, but not all are aware that the organic matter that makes up those plants, or biomass, is also a tremendous energy resource. Energy from organic matter can be used for fuel, electricity, and needed chemicals. These are all referred to as bioenergy, which is energy from life itself.
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.
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.
Replacing energy that cannot replenish with renewable energy sources will have beneficial effects on the economy. Those who work for an industry that is guaranteed to deal with shortages and eventually exhaust its resources probably find it difficult to relax and feel comfortable about their financial future. However, when people work in the renewable energy industry, they can be certain that renewable energy will always need to be collected and maintained. Instead of investing in resources that are drained from countries thousands of miles away, investors will invest in an energy that will continue to renew.
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.
