The Energy Source Of Renewable Energy

Energy is an important part of life producing the power of movement, heat, and production of electricity in many different ways. Therefore, choosing the correct source of energy is important for the environment and humans. Renewable energy that produces electricity never runs out, causing a lower environmental impact. Solar, Biomass, Wind, Geothermal, and Hydropower energy should be used globally to produce electricity. On the other hand, producing electricity from nonrenewable energy sources can be very harmful to humans and the environment. Humans can easily be dependent on it, which may not be the best option when it comes to finance, efficiency, sustainability and more. Approximately 52% of the US electricity comes from polluting sources like natural gas, oil, nuclear, and hydropower that have a lot of disadvantages effecting the environment in a negative way.

These alternatives can be helpful in reducing carbon emissions while ensuring the energy independence . These sources are wind ,solar ,geothermal, hydro, nuclear and renewable bio fuels. Some of these sources are renewable , meaning they can be replenished, while others like nuclear, are non-renewable, yet are clean sources of energy. For better sustainability , society continues to explore the challenges of these energy options to help implement the necessary changes for an environmentally friendly and energy independent future.

Everyone uses a lot of power for lighting, heating, machines, movements, and so much more. All of that energy has to come from an energy supply. Some energy resources are renewable, while others are non-renewable. Energy has various forms and is a very essential part of our everyday lives.

Renewable energy is considered an environmental friendly way of producing energy; according to http://www.renewableenergyworld.com/index/tech.html, “in contrast, the many types of renewable energy resources-such as wind and solar energy-are constantly replenished and will never

Currently in the U.S. we rely on non-renewable sources to produce our energy such as oil, coal, natural gas and nuclear energy. Although these methods do well producing energy, they also have large down falls environmental, economically, and in other ways that fail to show a promising future. This makes it necessary that we adapt alternative renewable energy methods that do not have these effects, and can insure a promising future.

Renewable energy sources are good for the environment but some people frown upon the idea of having renewable energy sources. They are more expensive than fossil fuels and nonrenewable energy sources. A Lot of energy needs to be put in both the research and manufacturing of nonrenewable resources. Renewable energy sources are cheaper because of the energy source already having the components in order

Also after World War II, a new form of energy production was discovered; nuclear energy from nuclear fission. As time went on, we've learned how to use energy more and more efficiently over the years. However, these sources of energy are called non-renewable for a reason. We would eventually run out of these sources and have no other ways of generating energy. "If we use fuel to get our power, we are living on our capital and exhausting it rapidly. This method is barbarous and wantonly wasteful and will have to be stopped in the interest of coming generations." - Nikola Tesla. We would eventually have to invent a whole new form of energy generation called renewable energy. Over time, we've developed new methods of harnessing energy from other sources; using the heat from our Earth(geothermal energy), creating energy from the sun(solar energy), using wind to create energy(wind energy), or using a river current to generate energy(hydroelectricity). Power plants that use renewable energy have only grown more over the years, but despite being more eco-friendly, non-renewables still dominate in energy

In the past hundred years we have been relying on fossil fuel as the major sources of energy, until now people are starting to see what harms fossil fuel does to our environment, and people are staring to see that we are running out of this sources, but likely with the advancement of technology scientist have been able to find something that will replace fossil fuel, and help clean our environment. This replacement are Alternative energy sources. These sources can be described as energy that will be less harmful to the environment as well as humans, cheap, and comes from sources that we won't run out of. One of the most popular source of alternative energy is solar energy. Solar power is the energy

Sustainable energy, also know as renewable energy, is energy that can be replaced. It can be made from the sun, the wind, plants and more. Unfortunately, sustainable energy is like foot note in the global energy plan, which is largely made of up of fossil fuels. Fossil fuels, are power sources like, oil, gas, coal, these all come from the earth and are in limited supply (ie. can run out). Also the extraction of such fuels can have devastating effects on the workers extracting the fuel and the environment the fuel is found in. It is because of the limited supply and ecologically damaging side effects of fossil fuels is why there is a large interest in sustainable energy, especially sustainable electric energy (Selin, Rafferty, & Pallardy, 2008).

The fact that 86% of our energy comes from nonrenewable, polluting, costly fossil fuels and only 14% is renewable is diabolical. Why must we harm our environment to contribute to our energy production when renewable energy sources are so abundantly present so that we may be symbiotic with nature? To lessen our environmental impact and be able to avoid the high expenses of non-renewable fossil fuels in the near future it should be obvious that we start to use more renewable energy sources than we do nonrenewable resources for apparent reasons. It’s the only answer, as we have already contributed to the now unstoppable melt of the glaciers in Antarctica soon to raise the sea level, according to scientist, four feet higher (Coghlan "Collapse of Antarctic Glaciers").

The earth has lots of energy sources such as nuclear energy, fossil energy, and renewable sources. Solar, wind, geothermal, and water are renewable sources of energy. These energy sources are clean. They do not produce any pollution. But the most reliable energy source is the sun. The sun is an important part of living things. It produces an energy called solar energy. Solar energy is the earth’s main source of energy which can be transformed into heat and electricity. Its energy was used to heat and to light homes during the earliest centuries. Without the sun, living things on earth would not surely survive because it would be extremely cold and dark. According to the article “Solar Energy,” every year the sun carries an average of 1.5 kilowatt-hours of energy to the earth in the form of visible light, X-ray, ultraviolet, and infrared radiation (Solar Energy). Solar energy can be converted into electricity in two ways. The first one is with the use of solar thermal or electric power plants that creates power by concentrating the sun’s energy to heat the liquid and produce steam which is used to power a generator. (Solar Explained). This is mostly similar to coal and nuclear power plant.

As of right now China is the leader in clean energy usage. They have been dramatically increasing their spending on clean/renewable energy source such as wind turbines, solar-photovoltaic cells, and water turbines. This rise of renewable and clean energy in china has come with a hefty price. China has spent almost $500 billion on renewable energy sources. With this increase of clean energy China is also reducing their use of coal and trying to get more coal plants to clean the coal so that there will not be as many pollutant coming from the plants. China has made a plan for all this to be possible, it will span over 5 years and it is planned to cause 20% of all energy used to be from renewable energy sources. Because of Chinas determined plan to make a big change in clean/renewable energy they have become the leader in clean and renewable energy usage, over doubling the amount of energy the US has produced from renewable energy sources.

Green power or green energy is the electricity which is produced from renewable sources and such renewable sources must be non-polluting. Earth has a self-cleansing mechanism capability which cleans or recover the environment naturally upto a limit, so pollution within that limit can be termed green. “The electricity produced from solar, wind, biogas, geothermal and low-impact small hydroelectric sources are referred to as green power or green energy as defined by U.S. EPA.” Many Consumers purchase green power to avoid harmful environmental impacts and also to benefit the environment by greenhouse gas reduction. [1]

Renewable energy is energy generated from natural resources—such as sunlight, wind, rain, tides and geothermal heat—which are renewable (naturally replenished). Renewable energy technologies range from solar power, wind power, hydroelectricity/micro hydro, biomass and biofuels for transportation.

Nowadays, with the continuous increase in the demand for energy consumption resulted by both population and socioeconomic growth, making it a priority to satisfy such a demand for all developed countries. This report aims initially to focus on the energy situation in the United Kingdom, and then present two forms of energy conventional energy in specific coal, and renewable energy which is wind energy, and will finally recommend the most suitable one after comparing and contrasting them considering both the cost and environment in different aspects.
