used to grind grain. Then‚ the wind turned large "sails" which were connected by a long vertical shaft that was attached to a grindnig machine or to a wheel that turned and drew water from a well. Today’s turbines - can utilize the energy of the wind to turn large metal blades which in turn spins a generator that manufactures electric power. Windmill electricity turbines‚ unlike the machines of old‚ are mounted on very tall towers in order to capture the most wind energy available. At 100 feet (30

In late 2005‚ NRG Energy bought Texas-based Texas Genco from a group of private equity firms for a price of roughly $5.9 billion.[4] Today‚ NRG has 29 traditional gas‚ coal‚ and oil power plants across 11 states‚ including 9 in Texas. Additionally‚ NRG currently has 6 operational "clean energy" facilities including wind farms‚ a solar farm‚ and the South Texas Nuclear

In our modern society there is a constant give and take environment over energy. The use of fossil fuels and coal has become politically incorrect in our green-centric society. The use of media and spin is one of the most important tools being used by companies that make use of fossil fuels. There is an economic incentive for these companies to downplay the potentially harmful nature of these energy sources. While the usage of coal and other fuels is easy‚ it is also seen by many as environmentally

This event could have been avoided entirely by relying on renewable resources such as nuclear‚ geothermal‚ wind‚ and solar power. Renewable resources are a great key for success because of their availability‚ cleanliness and overall safety. Renewable resources are available in vast amounts‚ most of them can never be depleted and they are very clean sources of energy

bye finding new ways to power our world. However‚ this is not just a scientific and political problem; this is something that affects every one of us. Domestic oil and natural gas has become very expensive over the past few years. Paying for higher gas has caused many families to look for ways to cut back. Some argue that the country must decrease its dependence on oil and invest in alternative sources of energy‚ such as wind and solar power. Using wind to create power is something that is said

There are many different types of green energy such as wind energy‚ solar energy‚ and hydroelectric energy. Each type of energy is very diverse in the way it affects our society. “Last year‚ wind energy added nearly half of all new power capacity in America. So let’s generate even more‚” stated Barack Obama in 2012. Wind energy occurs by spinning
