Benefit Of Renewable Energy

Hydropower or hydroelectricity is one of the more mature forms of renewable energy technology and can be found in some form in over 160 counties ("Hydro Energy", 2016). Power is generated when the kinetic energy of flowing water from sources such dams, rivers or waterfalls is directed through water turbines which in turn create electrical energy. There are over 120 hydropower stations though out Australia generating 8% of total energy generation ("Hydropower", 2016).

Renewable energy is energy that comes from any natural process and can be quickly regenerated. Some of the most common forms of clean energy include solar energy, wind energy, and hydroelectricity. These types of electricity are gathered through technology such as solar panels, wind turbines, and hydroelectric dams. Other types of renewable energy less known include geothermal energy, biomass energy, and energy collected from ocean (Renewable). Geothermal uses the Earth 's heat to generate energy while biomass use plants and other organic materials to make energy and fuels. Ocean energy can be derived from a multitude of areas. Energy can be gathered from the tides, the wind, and can also be gained from the

Renewable energy is considered an environmental friendly way of producing energy; according to http://www.renewableenergyworld.com/index/tech.html, “in contrast, the many types of renewable energy resources-such as wind and solar energy-are constantly replenished and will never

Jason M. Everett claims that “The kinetic energy in the wind can be used to turn a propeller-like wind turbine connected to an electric generator. The generator converts the kinetic energy into electrical energy, which can then be used to power a wide range of things.” Because of this, “Wind energy comes from the sun. As solar radiation heats the earth’s surface, hot air rises and cool air fills the voids. This air movement is defined as wind energy. Wind that is harnessed via mechanical means is also referred to as wind energy.” Jason M. Everett states

Renewable forms of energy are becoming more and more necessary for a sustainable future. Wind energy is a form of energy that is becoming more and more popular, and it offers a way for people to harness energy from something natural to create electricity. Wind energy in addition to other sustainable forms of creating energy are going to start taking the place of fossil fuels as people realize the true benefits of using them.

There are several methods of generating power using renewable sources. One example is generating power from solar cells. Solar cells are able to convert sunlight directly into usable energy by agitating electrons using the heat from the sun. This is called the photovoltaic effect (Types of Renewable). Today, a typical solar panel can convert about 15 percent of sunlight, but when they first started being produced in the 1950s, the average efficiency was only around 4 percent (Types of Renewable). The technology and methods are always advancing and improving. Thin film solar panels use layers of semiconductors only a few millimeters thick, allowing them to be used as roof shingles, tiles, and building facades (Types of Renewable). Apart from using solar panels to generate electricity; they can be used to save energy. Solar water heaters use the sun’s energy to heat water tanks so a house’s main energy grid does not have to.

The threat of global warming is influencing people to become “greener,” turning to renewable energy options which are often referred to as alternative energy. Renewable energy refers to energy that does not come from burning of fossil fuels or pollutant infused methods to provide energy. It is the harnessing of natural resources that are constantly renewable such as sunlight for solar panels and wind for wind turbines, just to name two (Lamb, 2015). The use of renewable energy is not only beneficial to the preservation of traditional energy sources but to environment and humans and lastly it economically will become a better option for people. Renewable energy is the key to a healthier future.

The term, “non-renewable energy,” is at its most basic form, means that the sources of energy will eventually one day run out and not replenish itself. Non-renewable energy comes in many forms. For example: coal, crude oil and natural gas. These sources are categorized as fossil fuels, meaning that they were formed in the past due to natural processes from dead organisms. Non-renewable energy has been proven to be very beneficial to the US, however, many people argue the negatives are not worth the benefits.

Wind power is produced by using wind generators to harness the Kinetic energy of wind. (wind power) Large groups of wind turbines are called wind farms. (Energy facts) Modern wind turbines have three blade can reach speeds at the top of over 320 kph (200 mph)

The science and technology behind wind power; the wind turbine is used to transform the kinetic energy from window into electrical energy that can be used in house holds. This is completed by the wind turbines pushing air between the blades of the turbine and rotating the blades, the kinetic energy of the air is transformed to the mechanical energy. Excess kinetic energy will be left in the wind as it travels away from the turbine. The mechanical energy is than transported to the generator from the shafts and gears in the wind turbine- this is the process of how the electrical energy is made. (Stelr,2017)

As another renewable energy widely used, wind power, which is now mainly used for generating electricity today, has been used for thousands of years powering human activities. Unlike solar energy previously mentioned, wind is caused by the uneven heating of the earth’s surface by the sun so that wind energy is an indirect form of solar energy (Volker, 2005). Wind is called a renewable energy source owing to the infinite sun shines.

The term “renewable” in the context of energy sources means that it can be utilized without depleting or weakening the supply. In other words, the earth creates that resource at a rate faster than we can consume, therefore, we can use it without affecting the atmosphere and other natural resources. Numerous forms of renewable energy that have been discovered and are now utilized, the two types I have decided to extensively research and focus my post on are wind power and geothermal energy.

Advantages of wind turbines is the wind is free and can be captured efficiently with modern technology, although wind turbines are

Energy in its various forms plays a big role in the world we live in today. From electricity powering our televisions to the gas lighting the fire in our stoves, our society is more dependent on energy than ever before. Energy comes in many different forms not only electricity; solar, chemical and thermal energy are examples of this. It can be separated into two groups, nonrenewable and renewable. Nonrenewable energy refers to a resource, which once consumed, cannot be replaced. Fossil fuels are a source of nonrenewable energy, however, they are already becoming scarce, this is where renewable energy comes in. Renewable energy comes from a source which when used, is not exhausted. Solar and wind are the most commonly known forms of renewable energy (The Definition). The demand for energy has increased as our population has grown, and will continue to do so. If renewable energy is not used more, the lifestyle we have today will suffer drastic changes, as resources such as oil and other fossil fuels will run out.
