Renewable Sources of Energy
What is a renewable source of energy?
Energy is essential for life. We use it in factories, in cars, airplanes, trains and ships. To heat food, light our houses etc. However, energy consumption is different in different countries. Since always human beings have used energy sources to do work or produce heat. Firstly, they used domestic animals or their physical forces. After, they used the wind and the water. Then, they exploited the use of fossil fuels and nuclear energy. In the near future we hope new energy sources appear. Among the different sources of energy, renewable energy is the one which is produced continuously and are inexhaustible at a human scale. The sun is the centre of all the renewable energy sources, as its heat provokes in the Earth the differences in pressure, which produce wind that is the source of wind energy. Hydraulic energy also comes from the sun. Plants do photosynthesis, live and grow. All that organic matter is the biomass. We do not have to forget of the sun, which is the source of solar energy.
Renewable sources of energy are based on natural cycles of the planet. They are the ones which are regenerated and can be replenished in a short period of time. They are so abundant that will last for hundreds or thousands of years. This means that even if we use them a lot, our children and grandchildren will use it as well.
The renewable sources of energy used responsibly do not destroy the environment. Electricity, heating and cooling are generated by renewable energy sources such as sun, wind, agricultural residues or organic. The increment in the use of renewable sources of energy ensures a maintained generation of electricity, reducing CO2 emissions.
They can also provide employment opportunities in rural and urban areas. They are sources which respect the environment which means that they do not have a negative effect on it.
According to a study on "Environmental Impacts of Electricity Production" environmental impact in the generation of electricity from conventional energy is 31 times higher than the impact of renewable energy.
Renewable energy plays an important role in the supply of energy. When renewable energy sources are used, the demand for fossil fuels is reduced.
Unlike fossil fuels, non-biomass renewable sources of energy (hydropower, geothermal, wind, and solar) do not directly emit greenhouse gases which affect the atmosphere and harm the living beings.

    As human beings, we need energy for just about all functions associated with the luxuries of our daily lives. We need energy to heat our homes, to fuel our cars, to watch television in addition to industrial and agricultural purposes. How often do we stop and think about where all this energy is coming from? Energy is formed and disbursed through an industrial process that is performed using a number of different sources. Although there are a number of different sources, there are only two types of energy, renewable and nonrenewable. Renewable energy sources are naturally replaced in time. Because of this factor, there is little concern with running out of these energy resources. On the other hand nonrenewable energy resources are quite the opposite. These resources have the potential to run out because they are not replaced naturally in short periods of time.…

    The difference between renewable and non-renewable resources is essentially quite easy to grasp. Renewable resources are simply ones where they are constantly renewed or in other words restored (Berg&Hager,2007). The types of renewable energy that exists today are ones such as wind, solar and geothermal and hydro or tidal energy. Solar energy and Wind energy out the four are easily the ones with the most benefits and seem to be the most popular. According to the GAO ( United States Government Accountability Office), wind energy has the potential to provide electricity to homes and business without further polluting the air and causing more depletion of non-renewable resources. It is by far the most efficient due to the operating costs being much lower then the actual costs for the energy from fossil fuels(GAO, 2004). Solar energy is the next most energy efficient, with the next alternatives being geothermal and tidal. Consequently, non-renewable resources are those that can not be replenished or renewed. Most of these resources are fossil fuels like, coal, oil and gas (Berg&Hager,2007). Unfortunately, a massive percentage of all the North America’s energy is produced by fossil fuels and over…

    Any energy resource that is naturally regenerated over a short time scale and derived directly from the sun (such as thermal, photochemical, and photoelectric), indirectly from the sun (such as wind, hydropower, and photosynthetic energy stored in biomass), or from other natural movements and mechanisms of the environment (such as geothermal and tidal energy). Renewable energy does not include energy resources derived from fossil fuels, waste products from fossil sources, or waste products from inorganic sources (Texas Renewable Energy, 2014).…

    Renewable Energy

    In recent decades, there has been an increased need to produce sufficient renewable energy to support global population growth. In response, it has become crucial to find socially responsible sustainable energy resources that offer energy security, reduce greenhouse gas (GHG) emissions, and do not compromise biodiversity or sustainability of existing resources. Despite efforts to reduce the amount of waste produced, a continually growing population limits the space available in landfills. Municipal and industrial waste biomass is often rich in organic matter, allowing for the creation and use of biofuels as an energy source. This organic matter can be used to synthesize ethanol, methanol, and biodiesel through the conversion of inorganic compounds into energy-producing organic carbon compounds. Moreover, unlike fossil fuels, which take millions of years to form, these organic carbon compounds are formed relatively quickly. Biofuel production from waste is beneficial as it allows for better management of landfill sites, and energy production from materials which typically cannot be recycled or composted. Most importantly, it allows for the reduction of significant amounts of methane produced from landfill gas emissions.…

    Energy is an important part of our everyday lives. Energy can come in many different types, and forms it can be used for many different purposes. Energy has many different usages and can be converted from one form of usage to another form of usage depending on what the need is. One form of energy conversion is the use of food to supply people's bodies with energy. Another form of energy is how coal is converted into electricity. Fuel is another form of energy that can be used for many different usages as well. Fuel is used for much different reason such as allowing our cars to function and our lawnmowers to cut grass. There are many different reasons why people use energy in the many different ways that we use it. Even though people rely on energy usage, some of the forms of energy we use are very harmful to the environment and even dangerous to ourselves. The harmful and dangerous fuels that we use can be changed to alternative methods of energy usage. There are two different types of alternative energy, which is known as renewable energy. Renewable energy is very resourceful and is able to be used because it is all around us there will not be a shortage of material and it is safer on every living thing and being. Energy and fuel usage just like everything else in the world has its advantages and disadvantages about using it. We must collectivity figure out which source of energy is right for everyone but for now we will find out which is best to use in your…

    What is so great about renewable energy? Well, because its renewable. Renewable energy will last forever and it cost close to nothing to get it. But it will always be their, unlike coal that once its gone, its gone. I think that the best process to get renewable energy is through geothermal plants. Some scientists think that the amount of geothermal energy stored in the earth will outlast our energy consumption and it may even outlast the sun. (Energy Informative) Geothermal is the most cost effective way to get energy, with one of the least amount of risk of damaging the environment.…
