Essay About Renewable Energy

1231 Words5 Pages

2.1 LEARING ABOUT RENEWABLE ENERGY: Can you imagine life without television, cars, or computers? What if you had to cook your dinner over a fire or fetch water from a river? It might be fun for a camping trip, but your probably would not want not want to do it every day. But that's how life was before scientists and inventors discovered ways to use energy to make our lives easier. Today, most of the energy we use comes from fossil fuels; coal, oil, and natural gas are all fossil fuels. Over millions of years, the decay of plants, dinosaurs, and other animals was formed into fossil fuels. These fuels lie buried between layers of earth and rock. The only way to get them out is to drill or mine for them, while fuels are still being created. 2.2 CONCEPT OF RENEWABLE ENERGY: Renewable energy sources also called non-conventional energy are sources that are continuously replenished by natural processes. For example, solar energy, wind energy, bio-energy-bio-fuels grown sustainably, hydropower etc. are some of the examples of renewable energy sources A renewable energy system converts the energy found in sunlight, wind, falling-water, sea-waves, geothermal heat, or biomass into a form, we can use such as heat or electricity. Most of the renewable energy comes …show more content…

Further, the pressurized steam from superheated water beneath the earth's surface can be used to power turbines and thus generate electricity. Although geothermal power seems ideal in that it is naturally occurring and does not require structures to trap of collect the energy (as in solar panels or windmills), it does have limitations. The greatest drawback is that naturally occurring geothermal vents are not widely available. Artificial vents have been successfully drilled in the ground to reach the hot rocks below and then injected with water for the production of steam. However, oftentimes the source of heat is far too deep for this method to work

    Throughout the centuries, humans have been attempting to find a way to power homes, cars, and other luxuries in the most efficient way possible. Coal and oil were two major sources that begin being exploited during the industrial revolution. Both have caused great controversy over the years from lawsuits to strikes. A new way to drill oil, hydraulic fracturing, was discovered and was an efficient means of drilling until its effects became prevalent. Also, when coal began to run out, a new method called mountaintop removal took hold, but continues to damage the earth.

    One of them is burning coal. The encyclopedia defines coal as a solid fossil fuel formed from the remains of land plants that were buried 300-400 years ago and exposed to intense heat and pressure over those millions of years. It is burned in power plants to generate electricity. Data says that 44% of the United States electricity comes from burning coal. The National Mining Association reported that in 2009, 55.4 percent of Maryland’s electricity came from it.

    When people are not aware of where their energy comes from, it threatens their values and ideals. Aldo Leopold discusses these dangers in his essay, Good Oak, suggesting solutions to prevent them and improve the environment in the process. Energy powers many of the things key to life. As pollution and environmental destruction become a more imminent threat, humans must control their use of energy, preferably making sure not to use more than is necessary to sustain them. People who do not fully control the sources of their energy may take it for granted and waste it, however if they make changes in their lifestyle, these dangers can be avoided.

    In today 's society almost everything that we use in our everyday lives requires some kind of energy source. With our reliance on these sources growing exponentially we have started to become more dependent on other countries to supply our fuel. With this dependence countries debt continues to grow and this has a very negative effect on the country 's economy. Energy can be split into two main groups renewable and nonrenewable. The difference between these two is the fact that one we cannot exhaust and the other we only have a limited supply of.

    It is fair to say that most would not want to live in a world without electricity, but if society cannot agree on an energy to use, this imaginary world could become a very real way of life. “Citizens and community members everywhere are seeking smart solutions to our biggest problem - the ecological collapse” (“Top 10 Pros and Cons” 1). The United States’ economy has been fueled by fossil fuels since the Industrial Revolution in the 1800s. Then, the early 1900s introduced a new, versatile source, oil. Through the 1950s, most Americans viewed rapid economic growth and high consumer spending as positive trends but this prosperity was fouling air and water and damaging natural resources.

    Due to these issues, renewable resources should become our primary source of energy. First, there are many issues with the energies sources we use now, but one of the major ones is that nonrenewable resources cannot replenish fast enough to replace what is being consumed. Energies made from fossils are the most common types of nonrenewable resource. Specifically, the three main types of fossil fuels are coal, natural gas, and oil.

    It is commonly known throughout human history that the energy used is burned from coal which creates biomass. During the Industrial Revolution, coal was an essential need to everyone, hence the discovery of oil as a substitute. Yet, the mass formation from the unearthing of oil causes more damage than benefits for the planet. Humanity had never seen a more compatible source in which came a higher demand for oil. As the public has urged to generate more oil, scientists theorized that fossil fuels will eventually run out, making way for a renewable energy route in the future (Mason).

    wind energy and solar energy are both renewable types of energy they create no pollution and are fully sustainable as they are both powered by natural sources and if there is no wind one day the solar panels can generate energy and if it 's cloudy another day the windmills can generate energy also the energy created during the summer can be sold to the grid for extra capital that can be used for field trips, renovations, etc. Geothermal heating systems are rated the most efficient and eco-friendly heating systems. The system works using buried coils that contain a liquid, typically a mix of water and antifreeze. The liquid is warmed to the same temperature as the earth and then runs through to the home where a compressor extracts the heat but not only that geothermal heating requires no fossil fuels so it is very eco-friendly LED lighting is an efficient and eco friendly lighting alternative because they waste much less energy in converting to light compare to incandescent lights which waste 90% of the energy to convert to heat not only that LED lights last up to 15-25 times longer that traditional light bulbs this makes LED a much better source of lights than others because it wastes less energy and it is more efficient at doing its job this is so much better for the environment because it uses less energy that other lighting sources

    Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves, and geothermal heat. It is the energy which is abundant in nature. The sun is the ultimate source of energy. Almost all the energy that we use eventually comes from the Sun. The exception is the heat of radioactivity deep inside the Earth, which is ultimately responsible for processes taking place inside the Earth.
