Essay about Renewable Energy Systems

In recent years there has been great concern over the growing demand for energy, and the lack of non-renewable energy resources to meet the demand in the future. In addition, the question of “sustainability”—the ability to balance social, economic, and environmental needs in energy production to meet both current and long-term requirements—has come to the fore. It is clear that America must expand energy production quickly, and that we must develop renewable, sustainable energy sources to meet long-term demand and protect our future. There are many proposed solutions, such as wind and solar power. But the technology for these resources is not yet fully developed, making them, at best, low-output alternatives. Because renewable sources are

Have you ever wondering where your electricity comes from? How your car uses gasoline to run? What about how these things impact our environment or how we are going to keep producing them? As a country, we need to start looking ahead to the future and planning for what is to come. Currently, 86% of America’s energy comes from petroleum, natural gas, and coal. All of these resources will run out eventually. We need renewable energy sources that will keep producing in a clean, more efficient way for a long time. Before committing to an idea and going all the way with it, we need to compare all the different energy sources available to the U.S. and choose the one that is best for everyone.

The time has come, we’re running out of fossil fuels and we need an alternative. That is where renewable energy comes in; The best part about it is that it is renewable so it will always be available to us, and we can acquire this energy through solar, water, and wind power. There is a lot of controversy as to whether we should rely on renewable energy, because some say it is not cost effective. However renewable energy can pay for itself, is available nearly everywhere through various methods of obtaining it, provides numerous amount of jobs and economical benefits, and it will not harm our environment.

In todays world the demand for more energy to power peoples electronic filled lives is ever growing. Nations around the world are looking for ways to supply this much called for energy and are asking the question “should they make the move from traditional energy sources and turn to more renewable alternatives?” American has answered this question and is among the nations pursuing alternative energy sources.

Between 1990-91 and 1995-96, total fossil fuel subsidies in 14 developing countries that account for 25 percent of global carbon emissions from industrial sources declined 45 percent, from $60 billion to about $33 billion)…Within the past six years, India, Mexico, South Africa, Saudi Arabia, and Brazil also cut fossil fuel subsidies significantly…Many developing countries are also actively promoting energy efficiency and renewable energy.

Renewable energy’s increasingly greater power output has “made wind and solar more competitive with fossil fuels in many regions” (Warrick). In fact, renewable energy has improved so much, both financially and technologically, that many “developing economies will ultimately choose renewables over cheap coal”, enabling them to “skip over a generation of technology” (Warrick). Hydropower, geothermal energy, solar energy, and wind energy will only keep improving in power output until they inevitably become the best choice for electricity. Now that private tech companies have begun to back renewables, their technology is increasing at an extraordinary pace. With more prominent business leaders supporting renewables, the public is more inclined to accept them. People like Elon Musk, CEO of Tesla (and many other companies), fund and promote clean energy projects to raise popular support and develop new renewable technologies. Some people argue, however that renewable energy will never produce enough energy to power the entire United States. After all, “by 2016, wind energy accounted for just over 6.7 percent of U.S. electricity production” and solar energy sits at just “0.6 percent” (Renewable). While this number seems extremely low, it has been increasing rapidly. In 2012, “solar energy accounted for only 0.2 percent of the electricity

Since the gasoline and fuel oil shortages of the 1970’s, the topic of renewable energy has been

The International Energy Agency’s (IEA’s) preliminary estimate of energy-related CO2 emissions in 2015 reveals that emissions stayed flat compared with the year before, whereas the global economy grew (3). The IEA noted that “There have been only four periods in the past 40 years in which CO2 emission levels were flat or fell compared with the previous year, with three of those—the early 1980s, 1992, and 2009—being associated with global economic weakness. By contrast, the recent halt in emissions growth comes in a period of economic growth.”

Whilst it may seem a “no-brainer” to cease investment in non-renewable power and transfer our effort, resources and investment into developing renewable energy sources, the reality is that we have become so reliant and dependent upon non-renewable energy – particularly fossil fuels – that we must continue to use, develop, and invest in such energy to maintain the living standards that we enjoy today. In our short to medium-term future, and in spite of our ever-increasing scientific knowledge about the environmental price that we pay in using non-renewable energy, we must continue to invest in it. Let me explain why.

In the 1960’s and 1970’s a movement regarding the physical environment began, this movement focused on a few environmental issues and disasters caused directly or indirectly by pollution. As the years progressed, this movement grew into a multifaceted activist movement gaining more attention in the US, more often referred as “Environmentalism” or “Environmental Activism”. As the human race realized the physical environment is fragile and thus must be protected, scientists started to look for more efficient and ecologically safe energy sources. The introduction of renewable energy brought to light all of these issues, giving a viable alternative for the nation’s energy future, implementing resources that are naturally replenished and also, eco-friendly.

In contrast, some believe that renewable energy is a key factor involved in helping the economy to grow. Many jobs are created in the manufacturing and running of renewable energy plants. The renewable energy and energy efficiency technologies created 8.5 million new jobs and $970 billion in revenue in the year 2006 (Langwith, “Renewable Energy is Economically”). The American Solar Energy Society says by 2030 it could generate up to $4.5 trillion in revenue for the U.S and create 40 million new jobs. This would represent one in every four jobs (Langwith, “Renewable Energy is Economically”). This shows how vital it is to get renewable energy companies in the U.S. It is important to build a stable economy again and do it all while helping the environment.

In this day and age, we have new energy sources that could be used to power our homes and transportation. Wind and solar power are used all over the world, but are still used far less than fossil fuels. Most would say it’s not reliable or it doesn’t make any profit. While both statements are true, it doesn’t mean we can’t make a better future using renewable energy. In fact, the only reason we don’t use renewables for everything is that we don’t want to change. The hard truth is we need to change. Fossil fuels are great right now, but if we run out, humanity must have another source of energy.

This essay focuses on two renewable energy resources. First of all, biofuel is now accepted as alternative energy in worldwide. The figures continue upward trend in the biofuel production. ‘An annual growth rate of 6.8% from 2006 to 2030 is expected for total biofuels consumption in the transport sector’ (International Energy Agency: 2008 cited in Zhou, et al., 2009:S11). Significant leaders of the biofuel market are Brazil, the United States and the European Union. The results of research indicated that 92% of the world’s ethanol is produced by Brazil and US together, while 90% of the world’s biodiesel manufactured by the EU. In addition, several developing countries in Asia such as Indonesia, Malaysia, Thailand, and the Philippines have an enormous potential for biofuel production. Now these countries are

Energy is a critical component for every economy and society around the world. Energy is divided into two groups, nonrenewable (coal, oil, natural gas, and nuclear) with a finite amount found around the globe and renewable (hydro, tidal, solar, wind, geothermal, and biomass) that are constantly being replenished so that they will never run out (Green Energy Choice, 2011). The international economic impact of renewable energy is explored by examining subsidies, strategic policies, and comparative advantage of renewable energy.

Energy is a crucial necessity and with the ever increasing need for it and the high and fluctuating prices of oil, researchers are constantly coming up with newer and more sophisticated alternative sources of energy. However, energy comes at a cost, as it is either expensive or it possesses high health risks. This essay presents the concept of energy by discussing the two major types of energy, the various forms it could take, including renewable sources of energy, energy conservation and above all it talks about the safest and cleanest alternatives.
