Alternative Energy Essay

1293 words - 6 pages

Alternative energy is any energy source that is an alternative to fossil fuel. These alternatives are made to look at problems about some fossil fuels. The nature of what makes an alternative energy cause has changed a lot over time, as have arguments regarding energy use. Recently, because of the change in energy choices and changing goals of their advocates, defining some energy types as alternative is highly unliked.
Alternative causes of energy differ greatly in their costs and availability across the U.S. Although, water, wind, and other alternatives can look free, their costs come in collecting, tackling, and moving the energy so it can do good work. For example, to apply energy from water, a dam has to be built with the electric generators and transmission lines.
Alternative energy is currently accepted is that which is produced or recovered without the undesirable dangers are in fossil fuel use, normally high carbon dioxide emissions, an important factor in global warming. Historians of economies have examined the key transitions to alternative energies and regard the transitions as pivotal in bringing about significant economic change. Before the shift to an alternative energy, supplies of the dominant energy type became erratic, accompanied by rapid increases in energy prices.Wind energy is one kind of alternative energy.
We have been tackling the wind's energy for hundreds of years. From old Holland to farms in the United States, windmills have been used for pumping water or grinding grain. Today, the windmill's modern equivalent - a wind turbine - can use the wind's energy to generate electricity. Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor.
In the more recent years, wind is becoming a more appealing cause of renewable energy, because wind energy is the world’s best energy technology. Wind turbines set at sites with big, sturdy winds can economically make electricity without making poisons. The power in the winds rise quickly with its speed, which means that finding windmills in places with strong winds is dangerous. The strongest winds in the U.S. happen to be in Alaska, the western part of the U.S., and the Appalachians. Wind power now stocks at nearly 1% of the U.S.’s electrical needs, but size is getting bigger quickly. Nonetheless, wind will not give more to the U.S. electric supply later on, like hydropower it isn’t likely to supply all of the electrical need of the U.S. families.
While wind power helps our environment by making electricity without making poisons, there can be bad environmental impacts of wind power formation, inclusive of wildfire deaths. Although, more recent studies show that the number of birds and bats killed by encountering...
