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
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 20% of the world’s people who live in developed countries use 70 % of the world’s energy.
As the world's population grows, and the already extensive use of technology in our daily lives expands and grows deeper ingrained into our lifestyles, many people overlook the shortcomings of this type of life style. What is powering iPods, computers, and televisions? Currently, the world releases over 26 billion tons of CO2 per year. Americans release about 20 tons of CO2 on a per capita basis annually; however poorer countries limit their annual per capita emissions to less than 1 ton. Many people fail to realize how much of a monetary burden cheap and clean energy would relieve for the poorest two billion people of this world. Some would argue it could in fact be the biggest fundamental change this world sees, when we have a viable solution. Almost everyone in rich countries overlooks the cost of electricity due to the small portion of our budget it accounts for [1]. Wind will need to be part of the clean energy equation. Using wind turbines alone could redu...
Thermal power, wind, Hydel and solar energy are the main sources for generating electricity. With the passage of time, the consumption of electricity has increased proportionately with the increase in the world’s population. Due to decline in global economic situations, that includes inflation, unemployment, corruption and other contributing factors have made electricity expensive and unaffordable for the consumers of third world countries. The production cost and the supply cost have increased, and as a result many electricity generation projects stand pending. With the passage of time, conservation of energy has become a core issue for the world.
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.
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).
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.
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.
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 ef...
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 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.
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.
