Alternative Energy Sources
“In United States around half of million deaths each year are attributed to air pollution. It is estimated that air pollution each day kills three people in the city of Hong Kong. Air pollution also contributes to soil and water pollution. More than 15,000 people in the world die each day because of water pollution” (pollutionfacts.com). With these statistics, it is no wonder people are coming up with alternative energy sources. From energy to gasoline, there are many different ways to reduce these statistics. Some alternatives to energy sources are solar and wind power, alternative vehicle fuels and hybrid cars.
Photovoltaic solar electricity, or more commonly known as solar power, is an alternative energy source. Basically, energy is produced from the suns light. The most common for of solar energy is active solar technology. Different ways to access active solar technology are with solar panels, fans, and pumps (Philibert). For example, the panels on a person’s roof work by absorbing the suns light, converting it into energy and distributing it all over the house. A downside to this method of energy is that when it is dark or cloudy, the solar panels cannot collect sunlight.
A close relative to solar power is wind power. Wind power is another way to get energy. With this method, the energy is produced by wind. Wind turbines are a way to get energy out of wind. Wind turbines are just like windmills but more modern and sleeker in design. There are two types of wind turbines, horizontal-axis machines and vertical-axis machines (Deal). The more common of the two is the horizontal-axis machine. It is a three blade machine designed to face the wind. Inside a wind turbine is the generator. The generators job is to turn the wind blowing on the blades into electrical energy.
Providing electricity for houses and business does take its toll on the environment, however an even bigger cause of pollution are the toxic gases emitted from vehicles. “There is considerable interest in electric and hybrid cars because of environmental and climate change concerns, tougher fuel efficiency standards, and increasing dependence on imported oil” (Deal). Hybrid and electric cars are a way to reduce our carbon footprint. Many vehicle manufacturers are beginning to jump into the hybrid car craze. Some of the most popular hybrid cars are the Toyota Prius, Honda Insight and Ford Fusion. There is also the electric car that relies solely on electricity to get from point A to point B. the downside to these cars however is that they only get about 100 miles before needing to be recharged. Hybrids are different because they rely on a mixture of two sources, electricity and gasoline. Hybrids can get further than electric cars because of this reason. Electric and hybrid cars have a special braking system called regenerative braking. Regenerative braking causes the car to recharge the battery whenever the car is coasting or completely...
