Introduction Renewable energy is considered a revolutionary thing, something that can save us from peak oil and climate change, but is it really what it seems? Renewable energy can help ease our predicament. There are multiple ways to achieve this, including the use of newer, greener technologies such as wind, solar power, and biomass. The purpose of this paper is to educate, theorize, and discuss various aspects of renewable energy, such as its history, development, and the advantages and disadvantages of renewable energy. Ultimately, my personal reflection on renewable energy and, energy in general will be discussed. Renewable Energy There are several methods to implement renewable energy. You can harness power from multiple sources, such as sunlight, wind, rain, tides, waves and geothermal heat (Stover, 2011). These methods will be discussed later. The most sought after forms of renewable energy are solar and wind power. Believe it or not, as early as 1873, concern arose about the shortage of coal, which prompted experiments with solar energy (Kovarik, 2011). Solar technology was used for heating and cooling, but solar technology was far too expensive to build solar panel farms until around 1980 (Solar Star Technologies, 2012). Many people still think that solar energy is a fairly recent and new technology. With regards to wind technology, in the 1970’s, due in part to the Nixon administration’s energy policy, the first electricity generating wind turbines appeared. In 1975, the U.S. Department of Energy (DOE) funded a project to develop industrial-sized wind turbines (Nixon, 2008). As with most renewable methods of energy production, they are fairly new, or have not yet achieved widespread use.

In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.

In the debate of traditional energy vs. renewable energy the clear winner is renewable energy. Renewable energy is vastly superior over traditional energy because it decreases dependence on foreign resources, produces no emissions, and is not limited in quantity. Opponents of renewable energy are likely to argue that this is not the case and that instead, traditional energy is better because it creates job growth, is reliable during all hours and climates, and comes with a lower cost. These advantages however are either misconstrued or hardly outweigh the long-term positive benefits of renewable energy.
Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).
Geothermal energy is one of the oldest sources of energy. It is simply using and reusing (reusable energy) heat from the inside of the earth. Most of the geothermal energy comes from magma, molten or partially molten rock. Which is why most geothermal resources come from regions where there are active volcanoes. Hot springs, geysers, pools of boiling mud, and fumaroles are the most easily exploited sources. The ancient Romans used hot springs to heat baths and homes, and similar uses are still found in Iceland, Turkey, and Japan. The true source of geothermal energy is believed to come from radioactive decay occurring deep within the earth.
The year is 2200. The world is going through a fossil fuel shortage. Oil reserves are almost completely consumed and it is becoming impossible to find new fossil fuel sources. Not prepared for this event to occur, The United States, has no alternative options. As a result of the oil shortage, the standard of living deteriorates. Heat in homes, supermarkets full of food, and transportation, all basic necessities taken for granted, will be depleted because fossil fuels are used to power almost everything. The key to the prevention of this future is renewable energy. Unfortunately the support for the use of renewable energy is weak and ineffective. Unless the US puts forth effort to research and promote the use of renewable energy to consumers, conversion from fossil fuels to renewable energy will no longer be an option.
In the search for alternatives to fossil fuels, scientists and policy makers have focused on three options: nuclear power, energy from biomass; and a combination of wind, water, and solar power. Nuclear power, however, is much more costly and runs the risk of having it fall into the wrong hands where it could be turned into a weapon of mass destruction. The third option entails wind turbines, photovoltaic power plants and rooftop systems, concentrated solar thermal power plants,...
Understanding the environment would help you recognise the appropriate energy production system to use. Renewable energy is an alternative natural source to fossil fuels like sunlight, wind and geothermal heat. Wind turbines and photovoltaic panels are examples of energy production systems where the conditions of a particular environment has to be taken into account. If a building is located alongside or near
Why do we need to rely on renewable sources? Most of the energy that we use today comes from fossil fuels such as natural gas, coal, and oil. All of these resources are non-renewable, so you can finish one day. In order to have a better world and a healthy environment for the future, people are trying to obtain energy from natural resources instead of non-renewable sources. In the lecture “Renewable energy resources” (2014), Mistry focuses on some advantages and disadvantages of renewable energy.
The wind is an incredibly valuable renewable energy source and is in the forefront of renewable energy developments. It is used to convert wind energy into energy that can be harnessed and used via a variety of methods, including; wind turbines, windmills, sails and windpumps. For a renewable energy source, however, it is wind turbines that are used to generate electricity (see figure 1). Wind power has been used for this since the end of the nineteenth century, after Professor James Blyth of the Royal College of Science and Technology first attempted it (Boyle, 2012). However, It wasn’t until the 1980s that using wind power technology was sufficient enough to experience a rapid growth of the technology.
Energy can be put into two broad categories Renewable energy and none renewable energy. Renewable energy sources can be reused continually as they are abundantly found in nature. All of them are non-polluting but devices used to collect the energy may impact the environment adversely. They are free but producing storage equipment or converting them into another form of energy may be costly.
Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
