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 gen... ... middle of paper ... ...ls."

This project investigates alternative fuel source cars, such as Biodiesel, Hydrogen Fuel Cell, Natural Gas, Ethanol (e85), and Hybrid. I choose this topic when I realized how much people are paying for a fuel (gasoline) that only gives you 30% efficiency per gallon. This means that for every $100.00 that you spend on gas, you are wasting $70.00.
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
Wind has been used for energy for thousands of years. Throughout time many historical applications have used the wind to generate a specific task. For example, sails of a ship use the wind to propel themselves across the ocean. Another example is windmills which have been used for grinding grain and pumping water. The earliest known applications of wind used as an energy source came from Persia around 900AD. There, the wind was used to drive early windmills. Prior to the Industrial Revolution, wind power was used by the Europeans as a significant source of energy for. As time passed, use of wind as energy lost favor because it was not always available when it was needed, and it was difficult to distribute. “The first wind turbines for electricity generation appeared in the late nineteenth century in the United States.” “Modern wind turbines are several hundred feet tall.” For example, “a wind turbine that generates 1.6 mega-walls of electrical power is approximately 113 meters tall from its base to the tip of the rotor blade.” Wind turbines must be pla...
The sun warms up the planet but people can also use that to warm up their own house. Not only does the sun help with heating but it can also help with other renewable energy sources. The sun is considered the most powerful energy source because it makes wind, is part of the water cycle by evaporating water, and it helps plants grow (West). Solar power uses the dark blue, tile looking machines known as photovoltaic devices that gather the energy and convert it into energy (Wieman). Since the sun does not always shine on the same spot, people need to choose the location of these devices wisely. When they have the device in the right position then they can start gathering power. Solar power collects solar energy from the sun, then “converts that into sugar and starches which then break down to create chemical energy” (Heinrichs, 12). This seems as a wonderful but not many people realize how...
From the early times of human beings, trying to find ways to harness the suns energy for their daily lives , we have come long ways since the first solar panels now we have other ways to create energy but those aren’t safe they’re dangerous and hazardous to the environment. The future begins with change and we can’t do that if we’re still doing the same things to, burning fossil fuels and power plants are the main sources of today’s pollution. Solar panels are a great thing for this time in age, harnessing the sun’s rays for energy pollutant free air.

Wind is the fastest growing renewable source of energy in the world today. The prices for using wind farms are constantly falling and the demand for energy is always rising. Wind turbines have much higher efficiency percentages than solar arrays. The price per kilowatt of a wind farm is also much lower than that of a solar array; it is almost a third less. Building a wind farm takes much less time than a fossil fuel factory, and they can easily be modified to fit the needs of the area. In the race for renewable energy wind turbines are an economical, comparatively simple, and efficient way to harvest energy that will never run out.
The first widely used renewable source of energy is wind power. This energy source is created by wind turbines that convert the speed of the wind into electricity and mechanical energy. The speed of the turbine affects the amount of energy that is produced. As the turbine moves faster, more energy is produced. About 1.5% of the world’s energy is derived from wind power, but that number is expected to increase in the future (Frater, “Top 10 Renewable Energy Sources”). Wind power turbines that are placed in large open areas have the least environmental impact. An example of a wind power farm would be the San Gorgonio Pass Wind Farm in Riverside County, California.
... and monthly water filling. Solar energy is the cleanest and purest form of energy, allowing for cleaner air overall in our environment. There is great hope for a lot more solar panels to be installed worldwide. Solar is a viable alternative energy with solar panels becoming more affordable and more efficiently designed.
The sun shines upon Earth every day, yet no one thinks much of it. Solar power’s importance, though, is above what anyone could have ever imagined. There is active solar energy, which is when solar power is converted into light, heat, cause air-movement for ventilation or cooling, or store heat for future use. Less thought of, the other type of solar energy is passive energy, which most take for granted. Solar power provides life with heat, light, and now, electricity. Solar power also plays a role in 4 of the 5 areas of green technology: energy, green building, environmentally preferred purchasing, and green chemistry. All in all, solar power is quite a unique form of energy.
According to research done by Energy Trends Insider the use of wind energy used for electricity has grown substantially since 1990.
There are many types of Alternative Energy Sources. The different energy sources are hydro and solar power, wind, biomass and geothermal energy. Throughout the world people don’t recognize that we use every these energy sources day for our own personal use. The energy sources are not only free but they are also renewable. It is a little more costly to use these energy sources, but going green is what’s best for our environment. Using these alternative sources will create fresher air, eliminate over half of the pollution caused by fossil fuels, and protect our earth a lot longer. I’m going to explain these five expensive, but very worth it energy sources.
