The history of using energies dates way back into the neolithic era when early humans started to use coal as an energy source. Since then we have made extensive advancements in the energy field. The biggest advancements being, the advent fossil fuels and renewable energies. Fossil fuels are hydrocarbons, mainly coal, oil or natural gas and are formed from the remains of dead plants and animals.(SCIENCEDAILY). Renewables use earth processes to create energy. The many types of renewable energy sources available to us now are solar power, wind power, geothermal energy, hydropower, and biomass. The top 3 renewable resources are hydropower, wind power ,and solar power.
Hydropower is by far the most used renewable energy. It accounts for over 16 percent of the world 's net electricity production. The most common method of hydropower energy involves the building of dams on rivers and releasing water from a reservoir to drive turbines.(POWERTECH). The second most used and fastest growing renewable energy is wind power. Wind power uses wind to spin a turbine creating electricity. If used in ...

...ility. Renewable energy relies on the weather for its source of power. Hydro generators need flowing water, wind turbines need wind to turn the blades, and solar panels need clear skies and sunlight to collect heat and make electricity.(SOLARSCHOOLS). When these are unavailable we can 't attain energy from them. The current cost of renewable energy technology is also more expensive than fossil fuel technology. This is because it is a newer technology and as such has extremely large capital cost.
Renewable energy is definitely the way to go. There are are a lot of benefits to this system compared to fossil fuels. It is replenishable, stable, produces less pollution, and overall a better choice . If we would to keep the world going for aeons to come and not hand over the earth to the next generation worse off than it is now we need to switch over to renewables.

- Renewable Energy Sources. There is a kind of energy that it’s inexhaustible. This means that it’s expected to last for a very long period of time, enough for human life existence. However, this doesn’t mean that it will exist for an eternity. According to Parris, “The prospect of climate change has the world searching for alternatives to fossil fuel to keep our homes warm, our factories humming, and our cars moving”. (Parris). Renewable energy is its name.... [tags: Wind power, Fossil fuel, Renewable energy]

- The United States currently relies on coal, oil, and natural gas to run our everyday lives. These different types of fossil fuels are nonrenewable and will eventually dwindle over time, becoming too expensive or too environmentally damaging to retrieve (Renewable Energy World.com, 2015). Different types of renewable energies are being discovered to better our world today. These renewable energies are also called green energy, and come from natural sources such as sunlight, wind, tides, and plants (Stephanie Rogers, 2012)....

- Renewable energy sources have been found to cost more than the benefits that are received from the energy sources. There are many different resources that you can use including water, wind, solar, geothermal, and biomass. These energy sources can differ in cost depending on capital, fuel, and operations and maintenance. Some of these sources are not cheap to build but once they are up and running, they have no fuel cost. There are many reasons to determine when, where, or how an energy source is used....

- Imagine a world without electricity. There would be no lights, no internet, and no efficient communication systems. Electricity is a type of energy, and energy is a vital aspect of today’s industry and society. There are many ways in which energy is produced, and they are typically divided into two major categories: fossil fuels and renewable energies. The term “fossil fuels” refers to nonrenewable resources such as coal, oil, and natural gas that formed over millions of years from the breakdown of fossils....

- Currently, non-renewable sources based on oil, natural gas, and oil are harming the environment, animal’s and human’s health. These non-renewable resources are increasing the earth’s temperature, and the most challenge that confronts the future of our environment is the greenhouse effect that is caused by six main greenhouse gases; Carbon dioxide, Methane, Nitrous oxide, Hydrofluorocarbons (also known as HFCs), Perfluorocarbons, and Sulphur hexafluoride (United Nations Framework Convention on Climate Change)....

- INTRODUCTION Renewable energy is energy produced from natural resources such as, wind, sunlight, rain, tides and geothermal heat which can be re-used or replenished. Natural energies (renewable energies) have its advantages and disadvantages. The reliance on fossil fuel is reduced by the sources of renewable energy. Though the use of natural sources has many advantages over the use of fossil fuels, the cost of investment for it can be too high for some people. In this project, I will be highlighting mainly on the sources of natural energy and its advantages and disadvantages.... [tags: Energy]

- Biofuels and renewable energies sustainability analysis Introduction Our industrial society is mostly powered by fossil fuel [65.3% (2012 est)], with oil and natural gas being the key resources [79.17 million bbl/day (2014 est) and 3.43 trillion cu m (2013 est) respectively]. However, this is a non-renewable resource as it has taken millions of years to form. Human kind has been using fossil fuel since the early Bronze Age but it is not until the industrial revolution in the 18th century that led to their wide scale extraction....

- Introduction Electricity is generated by the use of energy. Before going further, it will be necessary to talk briefly on what energy is all about. In this modern day, the standard scientific definition of energy is the capacity to do work, which means ability to move an object against a resisting force (Boyle 2003). According to (Beggs 2009) a physicist or an engineer will best describe energy in a form of an illustration. I.e. consider a mass of 1kg which is raised 1m above a surface on which it was originally resting.... [tags: Energy ]

- Do you have to pay to put fuel in a vehicle. I know I do and it's becoming more of a large burden rather than just another small expense of living. It's safe to say that the majority of people owning motor vehicles dislike the constant fluctuation in the price of oil and gasoline. The four worst polluters when it comes to the burning of fossil fuels are the United States, China, Japan, and Britain (Editorial par. 3). At the rate at which it is rising now, vehicles are soon going to be a luxury because people will not be able to afford the price of fuel.... [tags: Fossil Fuels, Solar Energy]
