For example, we used to (some still do) use the wind energy to grind grain in old fashioned wind mills.. Nowadays, we usually use the newer term called “wind turbine”.1 About four percent of the energy created in the United States comes from wind energy,2 and over 100 countries are now following in this trend and produce energy through the use of wind. This not only shows that a wind energy has great potential in the future, but also how popular it already is. It can be said that the more countries there are that using wind energy the better it is for our world. It is better because wind energy is a sustainable energy source.3 Looking back already at around 1000 AD wind power used and spread around northern Europe, starting with Holland. In 1850 the first company was created which started building wind mills because of the already then
Energies we use a lot nowadays such as fossil fuel and nuclear energy are both nonrenewable energy, which produces a huge amount of waste. For nuclear energy, once it’s all extracted, then the nuclear plant will be out of use. (CFF, n.d.) Also, over 50% of the energy that are produced by gas and coal turns gets lost throughout the process, which turns into waste. (NZ Wind Energy Association, n.d.) Due to all those waste that nonrenewable energy creates, the number one cost-effective source of the new generation is wind power. Other than that, numerous countries had set high targets for the amount of renewable energy that they’ll achieve by 2020 and the World Wind Energy Association (WWEA) mentioned that the wind power will help the government a lot while they’re trying to reach their
According to the Energy Information Administration (solar vs coal 2), 15 years ago, the electricity industry made a huge shift towards renewable sources of energy because of its cheap availability and increasing popularity. The author also compared the coal and the solar energy of at this time as a new electricity generation. Both solar and coal produce energy, but solar energy is more beneficial because of its efficiency, construction cost, and is environmentally safe and healthy. Everyone needs energy for various purposes. The first thing to consider while choosing the energy for us is its efficiency.
Take an example from the world banks in the 1950s and '60s, huge hydropower projects. Making dam cast huge but produce less energy than expected. Their biggest beneficiaries are mining companies and aluminum smelters, while Africa's poor inequality increase. This means the world bank got benefit by mining but the people who want or need help couldn’t get much support from this project. Only the debt increased.
“In fact, estimates show America could get 20% of its electricity from wind by 2030 – about as much as we get from nuclear energy.” 1 Wind energys noise disturbs those who live close to a wind farm. Most of the time wind turbines are forced to operate depending on the wind speed. But running under half its amount means lower energy production. The flow of the blades and the cogwheels make most of the noise. Cogwheels make noise inside the turbines tower.
Not only are Nuclear Power Plants useful for electricity, but they are also highly thought of to reduce greenhouse gas emissions. Many electrical generation methods pollute the air by burning carbon-containing fossil fuels that create carbon dioxide. The Three Mile Island accident was not as expensive as other disasters. Hurricane Katrina was the most expensive United States disaster. It affected 19% of United States oil production and briefly increased gas prices.
“Nuclear power will help provide the electricity that our growing economy needs without increasing emissions. This is truly an environmentally responsible source of energy.” Michael Burgess Prior to the introduction of nuclear energy, fossil fuel was thought to be the only available source in producing energy. Although fossil fuel, such as coal, petroleum, and natural gas, contains high energy value, it produces too many harmful byproducts that ultimately pollute our environment. With the rising concerns over global warming as more and more greenhouse gases accumulate in our Earth’s atmosphere, many voice such opinions that new alternative, yet sustainable method must be adopted to produce energy. Nuclear energy is one of the several alternative energy sources that have been introduced ever since.
The first practical windmills were used in Sistan, early in the Middle Ages. Eventually they became used by many Asian and Middle Eastern civilisations, for example "by 1000 AD, windmills were used to pump seawater for salt-making in China and Sicily". We still use the wind to sail today In the 19th century, along with the beginning of the Industrial Revolution, we started to see even more practical purposes for windmills. We had started to provide electricity with windmills. In 1887, Professor James Blyth (a Scottishman) had begun to install his very own windmill,
Angel Hsu A block Solar Energy 12/22/2015 “Because we are now running out of gas and oil, we must prepare quickly for a third change, to strict conservation and to the use of coal and permanent renewable energy resources, like solar power.”(Jimmy Carter, televised speech,1977) Just like what he said, we should develop other energy than fossil fuel because we will run out of it some days and fossil fuels are the main reason of global climate change. Global climate change is a very serious problem that we must pay close attention to. The main reason that causes climate change is that there are too many carbon dioxide in the atmosphere. If the temperature keeps getting higher and higher, there will be many problems that can cause great damage to us and the environment. If we don’t replace fossil fuels with other clean energy, our Co2 level will be as many as the time of the dinosaurs and we don’t know what will our lives be if this really happened.
Domestic oil was being produce oil at 100%, but the production was still not enough to supply Americans demeaned. The Graph in PDF, displayed the energy consumption by source. It showed how much oil Americans were using and the beginning of the downfall in the United States, due to how much oil we used. Texas, Oklahoma, and Louisiana
Xel Energy, one of the power plant compony that use wind, generate a large amount of power for use at a low cost on money and environment. Obama’s climate action plan make the United States the leader of solving the problem of climate change. It called for the reduce emission of carbon dioxide, reform on the power plants, and use renewable resources. EDF works with other organization to help control and watch the change in climate and population. But the process of solving the solution problem and climate change is never easy.
