When the new Southeast Polk High School opened they added many new energy saving products. This included installing geothermal heating under the high school cutting back on the cost of heating such a large building. Many new windows help save on energy used to light the building along with automatic lights that turn off after several minutes without movement. The new high school shows how easy it is to save money and help the environment. Renewable energy is good for all aspects of the U.S, providing jobs, economical growth, environmental cleanliness, and new research for improving energy efficiency. Therefore the United States should use renewable energy to benefit the economy and environment.

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.

The United States has an extremely well developed and maintained power grid which in its current state is configured primarily for non-renewable power generation. As the cost of green power comes down there will be an increasing amount of green power generation on the grid. This new, cleaner source of energy unfortunately has disadvantages that more traditional methods of power generation don’t suffer from, namely consistently. Photo-voltaic cells will only work when the sun is shining and wind turbines only spin when wind is present. I will be examining the readiness for renewable power of the power grid within the United States as well as investigating improvements that would allow for a larger national power generation percentage of renewable

Energy is crucial to almost every major and opportunity the world faces today. From the perception of jobs, security, climate change, food production or increasing incomes, access to sustainable energy for all is essential for strengthening economies, protecting ecosystems and achieving equity.

In recent decades, much debate has ensued about the vast amount of natural resources and ecological services society depletes. Moreover, the debate has evaluated how society depletes these natural resources at a faster rate than the environment can replenish. It also assesses how society can mitigate these environmental issues in order to preserve our natural resources for the prosperity of future generations. Research suggests that the natural resources we currently use, such as coal and petroleum, could be fully depleted within the next 25 and 100 years respectively (Byrd, 2012). Given that society has a tendency to over-consume natural resources, many economists have suggested that the use of alternative energy could alleviate the

The term, “non-renewable energy,” is at its most basic form, means that the sources of energy will eventually one day run out and not replenish itself. Non-renewable energy comes in many forms. For example: coal, crude oil and natural gas. These sources are categorized as fossil fuels, meaning that they were formed in the past due to natural processes from dead organisms. Non-renewable energy has been proven to be very beneficial to the US, however, many people argue the negatives are not worth the benefits.

Edgecomb, ME is surrounded by many sparsely populated towns, this factor along with it’s location at the delta of both the Sheepscot and Damariscotta rivers leads to a high potential for utilizing renewable energy. Such conditions allow for potentially using many different kinds of renewable energy sources: tidal, hydro, biomass, solarvoltaic, wind, and geothermal. While all of these renewable energy sources have potential for use in Edgecomb, there’s a lot of different combinations of renewables that could power Edgecomb as well as the entire Sheepscot and Damariscotta valley. In Maine, just like any other place with the capabilities and potential to take advantage of renewable resources there

Bilen et al., (2008:1531) predicted that global energy consumption will account for around 85% of the increase in world primary demand over 2002– 2030. The increasing of global energy demand happens the global stock of fossil fuel resources may be adequate for short term period, thus requiring the development of renewable energy sources, which would not decrease the stock of fossil fuel resources available for future generation. There is an increasing interest in the development of renewable energies such as biofuel and wind power, which have a great potential energy to produce enough power for the world’s population demand.

As the world delves deeper into the 21st century and as more and more countries develop into industrialized or post-industrialized nations, global society is dependent on reliable and steady sources of energy now more than ever. This reliance on energy will most certainly continue into the future as the U.S. Energy Information Agency (EIA) has projected the world’s energy consumption to increase by 56% by the year 2040 (“EIA Projects World Energy Consumption”). Such a substantial surge in demand of energy in what is a relatively short period of time has disquieting implications. According to the British Petroleum Statistical Review, oil, natural gas, and coal consumption accounted for approximately 86% of the energy market in 2015 (“Statistical Review of World Energy”). With current oil prices being at record lows, a booming natural gas “renaissance” in the process of going on, and political pressures in the United States calling for an increase in “clean coal” output, nonrenewable fossil fuels may be the primary options for our society to fuel its future (Sontakke). However, these options come with adverse drawbacks such as dependency on dubious foreign petro-states and various forms of ecological degradation, which includes climate change. Due to these factors, as well as burgeoning cost-competitiveness, the renewable energy industry is poised to gain a sizable share of the energy market.

With the emergence of climate change as a worldwide concern in the past several decades, scientists and engineers have worked assiduously to develop better and cleaner ways to produce energy. Renewable energy systems have experienced unimaginable advancements in recent years to make them more efficient, but utilities still struggle with the storage of this energy for practical use. Different types of renewable energy are currently stored in multiple ways, which contributes to discrepancies among the comparative efficiencies of various sources of energy in different areas and situations. This paper will discuss how several major renewable systems store energy, and what combination of circumstances makes each of them respectively advantageous.

Energy is a crucial necessity and with the ever increasing need for it and the high and fluctuating prices of oil, researchers are constantly coming up with newer and more sophisticated alternative sources of energy. However, energy comes at a cost, as it is either expensive or it possesses high health risks. This essay presents the concept of energy by discussing the two major types of energy, the various forms it could take, including renewable sources of energy, energy conservation and above all it talks about the safest and cleanest alternatives.

Modern society is characterized by convenience; convenience supplied by oil. Whether it be to fuel cars, to make plastic for hair dryers, or to paint a wall, most everything found in use today depends on this black gold. Although petroleum ’s variety of uses has made life convenient, this convenience has lead to an extreme use of oil, and it is now leading to its depletion. Although billions of barrels of oil remain in worldwide reserves, the United States needs to invest in replacing petroleum with alternative energy sources because readily available oil reserves are running out and other sources are more difficult to access and use .

Abstract - With increasing load demand and global warming, an environment-friendly type of energy solutions to preserve the earth for the future generations has become a prerequisite. Other than hydro power, many such energy sources like wind and solar energy is highly potential sources to meet our energy demands. Systems which uses two or more renewable energy sources is is better than the single source system in terms of cost, efficiency and reliability. Standalone Wind/solar hybrid generation system offers a reliable and better solution to distributed generation for remote areas and localities where power from grid is not available. Natural energy-based power generation systems are always equipped with storage batteries to give

Having relied on conventional energy sources for so many years which cannot renew themselves at a sufficient rate for sustainable economic extraction, as well as the growth of energy demand causing global energy crisis nowadays, it is becoming clearer than ever that all the countries have to look for other alternatives to try to tackle this issue. Therefore, renewable energy is considered to be a long term solution that might be able to replace the traditional forms of energy in the future. For instance, in the UK according to the Department of Energy and Climate Change, (2012), the primary consumption of electricity increased by 1.2% in 2012, at the same time the production of fuel dropped by 7.3%, additionally, the Office for National Statistics predicts a population growth of 1.3% by 2037. This illustrates that with the growth of demand for energy supplying as well as the predicted
