Alternative Sources of Energy Essay

all around the world, people nowadays prefer something that is environmental, healthy, recycle and less pollution, that is why Green Design become so popular in this day and age. Green design can be defined as the ‘creation of buildings which are energy-efficient healthy, eco-friendly, comfortable, flexible in use and designed for long life’. Besides, Green design should have the least impact for the environment, both in terms of products and materials used in the construction but…

it states a summary of the act, “The Pollution Prevention Act focused industry, government, and public attention on reducing the amount of pollution through cost-effective changes in production, operation, and raw materials use. Opportunities for source reduction are often not realized because of existing regulations, and the industrial resources required for compliance, focus on treatment and disposal” ( http://www2.epa.gov ). However, the process of rebuilding the current ecosystems will take…

Wind energy should be used instead of fossil fuels. The demand for wind energy is increasing so the number of wind turbines needs to increase to keep up with the global demand. Wind energy costs are lower than the cost of fossil fuels. There are several reasons to choose wind energy over fossil fuels. There are many types of renewable energy sources, but wind energy is the energy resource of the future. The demand for wind energy is increasing, so this means that the number of wind turbines…

connecting the issues with his readers. He then provides his readers with a logical and reasonable argument that makes them re-think if junk food really is cheaper or easier. Bittman confirms his argument by using statements from other creditable sources Bittman’s argument sends a good and convincing message because it lets people know that the concept “junk food is easier and cheaper” is not always the case. With obesity on a rise its important that people know there is healthier options for…

converting chemical energy, present in the fuel, to mechanical energy. This kind of machine is used to generate power and make human life easier. Also engine is used in large scale around the word. However the fuel used in engines is a controversial discussion because it is from nonrenewable resources, which are being depleted at a rapid rate. Moreover, the combustion of fossil fuel releases many emissions in the atmosphere. In this scenario bio fuels are emerging as an alternative to reduce…

But instead of using heat energy to create steam to turn a turbine, hydroelectric dams use the energy generated by gravity on liquid water to turn the turbine. On one side of the dam is a reservoir which holds water at a higher elevation than the river on the other side of the dam. This relatively higher elevation is what gives the water the potential energy to turn the turbine when it begins to flow ("Hydroelectric Energy."). Potential energy is calculated by the force due to gravity…

They are equally not a significant source of energy for the body if there is sufficient alternative amount of carbohydrates and fats. Therefore proteins can only be used as a major energy source when the body lacks sufficient amounts of both carbohydrates and fat. However, this is not actually economical for the body due to the fact that tissue maintenance, growth, and repair become significantly compromised in order to meet the body's energy demands. Since the body is regularly renewing…

their shells and the harder it is, the more energy they spend and this can lead to them not having enough energy for other mechanisms or activities, like getting nutrients.…

incentives to find cleaner energies, like the cap-and-trade system. Instead, more focus should be placed on the energies that do not have so many negative externalities. States like Florida that outlaw solar energy leasing should change their policies in order to drastically decrease their pollution output from factories and homes (Dickinson). According to National Geographic, the sun beams enough energy each hour to satisfy global energy needs for an entire year. However, solar energy produces…

Thesis: Our energy comes predominantly from fossil fuels because of it’s supposed inexpensiveness. However, the cost of fossil fuels in terms of human lives is often ignored. Nuclear power, on the other hand, is a much safer alternative because it results in fewer deaths per unit of energy produced than coal and natural gas. By comparing their outputs in terms of energy produced per unit of fuel consumed, and comparing that with the amount of byproducts produced as well as the amount of deaths…
