Using Renewable Energy Essays

Some may believe that renewable energy is not beneficial. In contrast, some believe that renewable energy is a key factor involved in helping the economy to grow. Many jobs are created in the manufacturing and running of renewable energy plants. The renewable energy and energy efficiency technologies created 8.5 million new jobs and $970 billion in revenue in the year 2006 (Langwith, “Renewable Energy is Economically”). The American Solar Energy Society says by 2030 it could generate up to $4…

One of the greatest problems in recent years in America is the dilemma of alternative forms of energy. While all forms of energy have various pros and cons, some are much more favorable than other depending on renewability, reliability and cost. Some are extremely energy renewable, some are much cheaper than others, some are much more reliable and some take up a lot less space than others. There has been a lot of disagreements as to what the best source is, pro's and con's considered. All of the…

ecosystem there, as well. In sum, solar energy is easy to harness and extremely available in certain areas, but it can pose difficult challenges at times. Biomass is the energy found in most organic materials. For example, many plants including trees, straw and vegetables carry energy converted from the sun. When plants employ the process of photosynthesis to make their food (CO2 (g) + H20 (l) + energy from the sun–> O2 + C6H12O6(s )+ H2O (g)), some of the energy is stored within the plants rather…

the world's energy. The amount of energy used in the United States alone poses a problem when looking at alternative energy sources. “Renewable energy sources will have to be successful and as plentiful as petroleum to provide the amount of energy needed around the world” (Mathewson, 1999, p. 279-80). Renewable Energy: Is It Necessary? Petroleum is at the heart of almost all the energy currently produced. While it is easy to transport and use, many people forget the hazards of using fossil fuels…

then go to the electric companies for the difference in price from switching to renewable energy. (Solar Energy) Converting from fossil fuels to renewable energy is extremely expensive. Power companies in the U.S. have to decide to change their equipment to renewable energy or continue powering on fossil fuels. In China, companies have to buy the equipment anyways so it is not as hard of a decision. Renewable energy is expensive. It costs companies twice as much to use solar power than it does to…

Second, renewable energy systems make use of organic wastes, producing energy as well as cleaning the environment. For example, bio-diesel from unwanted cooking oil has saved approximately 1 billion of US gallons of petrol-diesel while helping thousands of local restaurant owners get rid of their wastes. (''Renewable Energy,''American Green). Clearly, the use of the waste in the environment keeps both the carbon dioxide pollution and the organic wasted shedding under control. Finally, renewable energy…

Renewable energy is as green as it gets as it is by today’s technical standards and it’s a marvellous method for fighting back against global warming. Fossil fuels are damaging the planet and this can be our way of doing something about that. The most important part is that renewable energy is commitment free and sustainable. It can be replenished so we can use as much of this power as we need and we can restock it or it will restock itself. The sun and wind are with us for the long haul. As sources…

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…

Other types of energy lie between kinetic and potential energy or are an amalgamation of both types. There are no definite forms of energy since possibilities of new forms of energy are limitless. However, the various forms of energy in physical science include thermal, chemical, electric, radiant, nuclear, magnetic, elastic, sound, mechanical, and luminous energies (Foland 13). Thermal energy or heat is the energy in random motion of particles. Chemical energy refers to the energy from the aggregate…

Chapter 1 Introduction 1.1 Motivation Recently, wind power has gained greater attention with respect to sources of renewable energy due to the maturity of the technology and its relative cost competitiveness. Wind power farms (WPFs) are scattered in remote areas (onshore and offshore) selected by the wind speed, water depth, and distance to shore. It is important to develop technology to monitor WPFs with higher capacities as the size and number of wind turbines in a WPF is continuously increasing…
