Recommended: Reflection about non renewable and renewable energy
As I going to write about the renewable energy the very first question arise in my mind is, “Why We Need Renewable Energy Sources?”. So first of all I want to put some lights on this.
Why We Need Renewable Energy Sources?
The world today faces an energy difficulty. Global population is rising rapidly. The world population was estimated to have reached 7.6 billion as of October 2017. The United Nations estimates it will further increase to 11.2 billion by the year 2100.More people means higher energy demand, but we can’t forget the more than 1 billion people today who already live without electricity.
We also can fulfill this demand of energy by non renewable energy sources such as, fossil fuels-coal, petroleum, and natural gas, nuclear energy etc. but there are major disadvantages in using this type of energy sources. Carbon is the main element in fossil fuels. By processing fossil fuels

Provide a sustainable energy source for billion people is a huge challenge. To complete this challenge, renewable energy sources has to be a larger portion of energy.
Advantages of Renewable Energy
It helps us to fight against climate change: Renewable energy sources do not or less emit greenhouse gases in energy generation process, that makes them the cleanest, most possible solution to prevent environmental degradation.
Endless: With compared to conventional energy sources such as coal, gas, oil and nuclear reserves are finite but clean energies are available from sun. This makes them an important element in a sustainable energy system that allows development today without risking future generations.
Reducing energy dependence: The local nature of clean sources gives local economies an advantage and make them “energy independence”. Everywhere in the world there is a renewable resource like wind, sun, water or organic material available for producing free
The 20% of the world’s people who live in developed countries use 70 % of the world’s energy.
FROM observation we have come to know, that more than 1.5 billion people around the world have little or no access to light due to shortage or unavailability of electricity. Large numbers of affected people are from rural areas, and to a certain extent people from urban areas are also getting griped into energy crises. Statistics from United Nations says, that an investment of about US$35 billion to 40 billion per year is required to provide electrical energy to accomplish consumer basic need of energy for light, cook and mobility. Even after such heavy investment 16% of the world’s population will still not have electricity by the year 2030 (International Energy Agency).
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.
The United States currently relies heavily on coal, oil, and natural gas for its energy. While the price of natural gas per barrel continues to plummet, the United States is constantly seeking new sources of renewable energy. Renewable energy consists of any type of natural resource (solar power, ocean power, wind power, rain, snow, etc.). that naturally and automatically replenishes itself. Renewable energy is important because it is infinite and everlasting, meaning our children and our children’s children will be able to utilize these resources long after we are gone.
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).
Instilling this new way of energy usage into off-grid communities will inevitably increase the state of living for those in cities and other well populated areas. The change to renewable energy sources could drastically lower the pollutants currently being dispersed into the atmosphere by coal mines and other harmful power options,
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.
"United Nations Environment Programme." Renewable Energy in China. United Nations Environment Program, n.d. Web. 23 Feb. 2014.
One of the most compelling arguments for the use of renewable energy is how many forms exist of it. Nuclear power, solar power, wind power, tidal power, hydroelectric power, pumped storage, wave power, geothermal power, biomass, and biogas are the most widely known renewable energy sources (Darvill, 2013). This large selection of fuels supports the idea of renewable fuels one day powering the entire planet. All the sources of energy have different niches and benefits. Solar energy is extremely effective when providing energy for small establishments such as a house or small store, but hydrothermal power would be a more plausible solution for factories or large establishments....
The world that we live into today affords us the expectation that the flip a switch will turn the lights on. As populations increase and developing nations undergo dramatic economic growth, this energy demand will only continue to grow. The International Energy Agency (IEA) believes that “the world’s energy needs could be 50% higher in 2030 than they are today” (ElBaradei). Given this projected growth, it is necessary for world leaders must take action to secure the energy supply. Meaning that world leaders need to start seriously considering an alternative to non-renewable energy sources. “In 2012, the United States generated about 4,054 billion kilowatt-hours of electricity. About 68% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 37% attributed from coal” (U.S. Energy Information Administration). The fossil fuels that are used to supply over half of our country’s energy are in finite supply and are increasing in price to astronomical heights.
For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
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 story of renewable energy back to old ages , actually any new energy found it become alternative to the last one was used . for instance ,when oil discover it’s became alternative to the coal, which people was use it for cooking and heating .then in 19th petroleum became an substitutional to the oil to generate electricity. Currently we defined the renewable energy as the energy comes from natural resources and never run out .
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.
