Although they can disturb wild life, cost a lot, and need plenty of researching, I think it's a great idea. As I addressed before, they work most of the time and provide lots of electricity with natural resources. I do care about the wild life, cost, and just people’s complains.
This gear is connected to a much smaller gear that spins much faster which powers the generator to make electricity. Wind energy is becoming more and more popular. In California, there wind farms have offset carbon emissions by 2.5 billion pounds. This would take 90 to 175 million trees to take this much carbon dioxide out of the air. Kits start around $1,000.
This report explores solar power as an alternate and superior means of power generation for homes. Discussion and Results “Photovoltaics—A Path to Sustainable Futures”, a journal article by Joshua M. Pierce states that since 1957, electricity demand in the US has increased by over 450% while the US population has increased by only 50%, which illustrates how the demand for electricity has grown. During the first half of the 20th century, the national average price of electricity decreased as more efficient generating units were brought into service and this general trend has continued, but more electricity is needed so there is a need for different methods of generation like nuclear and solar power. Nuclear and fossil fuel generation have many negative environmental impacts, so there is a need for change which enables consumers to reduce dependence on these harmful technologies. “Photovoltaics—A Path to Sustainable Futures” states that new technology such as solar power has become a primary focus for researchers and they not only believe solar power to be environmentally safer but more cost effective as well.
Fossil Fuels Fossil fuels are created from organic material that was created millions of years ago. Petroleum, a fossil fuel gets its name from two words, "petra" meaning rock and "oleum" which means oil. Petroleum is drilled in order to search for oil. Also to determine the size of a reserve, as well as to produce oil and gas at a controlled rate. There are different ways to recover Petroleum.

The large dams that are used for hydropower, can also control floods, which is a benefit for the people living downstream of the reservoirs. In conclusion, using hydropower, as the world’s main energy resource is a smart idea because it doesn’t create pollution, it has better flexibility and suitability for industrial applications and it’s the most efficient way of creating energy.
Wind power can be a foundation of that sustainable energy future because it provides jobs in states that are building wind turbines, is a renewable energy source, and does not damage our environment. The environment will not be damaged by the pollution, the natural resources will not be used up, and there won’t be generating of hazardous wastes. Welcoming wind energy today will lay the foundation for a healthy tomorrow that will affect everyone in the United States. There are obstacles and challenges that will make it more difficult, but the environmental impact is well worth it to invest more money into wind energy. As the wind energy industry continues to grow, it will provide many job opportunities for workers and job seekers.
The cost of wind power has gone down by about 85% making it more money efficient than fossil fuels (Natural Resources Defense Council) (Environment America). For instance, Walmart’s scattered across the United States have taken action by using solar energy saving a total of about $5 million so far (Apparel Resources. 2014). According to the American Wind Energy Association, $800 million dollars spent on renewable energy in 2007 manufactured a total of 11,200 megawatts while $1.2 billion spent on nuclear energy produced 0 megawatts of energy. By 2030, The United States will have collected revenue of about $4.5 trillion and acquired 40 million jobs due to renewable resources (American Solar Energy Society.
Fossil fuels are obtained by obtaining organic materials which are extracted from the ground. “Coal is the world’s most abundant fossil fuel, and it provides 27% of our global energy consumption” (329, Withgott, Laposata). Coal can be found in the ground and the only way to remove it is to mine for it, no matter if it deep underground or near the surface. There are different methods used when extracting coal. For coal deposits that are near the surface you use strip mining and for coal deposits that are deep underground you use subsurface mining (329, Withgott, Laposata).
“The energy used to build a wind farm is produced by that farm within four to six months. After that, the energy it produces is free.” (Oxlade) According to Tony Zamberlan the state of California and other places with a larger population have the price of 10 to 15 cents a KWH. “Wind is a fuel, and it’s free.” (Hosansky) In the United States alone wind power has created 85,00 jobs and 400 manufacturing plants. Wind power is one of the fastest growing manufacturing sectors. It is a large possibility that wind power could produce thirty percent of the world energy within the next fifteen years.
According to Eco Info in 2009, at the rate we are using fossil fuels at; we have an estimate of 46 years of oil, 63 years of natural gas and 119 years of coal. However if every Canadian home and every home across the world had solar panels they wouldn’t need to use fossil fuels to power their homes. Everyday solar panel technology is becoming much more efficient. “Every minute the sun bathes the Earth in as much energy as the world consumes in an entire year.” — (US Department of Energy web site, 2010). Now by harnessing this amount of energy the worldwide energy crisis will be solved.
