Renewable Electricity : Generating Electricity, Heating And Making The Food That We Eat

Nonrenewable energy sources are sources, such as fossil fuels like coal, which are extracted from the earth and cannot be replenished quickly. Renewable sources of energy are sources that there is a seemingly endless supply and/ or can easily be replenished, such sources are solar, wind and water to name a few. Commercial electric generation came about in the late 19th century and was

The modern world is run on electricity. From the lightbulb to the laptop the world is more wired then it ever was before. Yet most conventional ways of producing power produce green house gasses. This greatly contributes to global warming, which harms our environments and our homes. Hydroelectricity, derived from the water- electricity, is the practice of using kinetic energy stored as water in a dam to generate power for ___ needs without producing greenhouse gasses.

Nuclear power works by a process called fission. The type of fission used in most reactors is where a neutron collides with a uranium-238 atom, splitting it into krypton, argon, spare neutrons and heat. The spare neutrons start a chain reaction for more uranium-238 atoms to split. The heat produced by fission heats the water surrounding the fuel rods, which circulates through a pipe. The heated water passes through a primary loop, then passes through another set of water heating the second supply of water creating steam. The steam then passes through a secondary loop. The steam turns a turbine connected to a generator, creating power. The steam in the secondary loop then passes through a pipe which runs through cold water, cooling the steam into back to water. Then dumps it into a river, lake, or ocean. The amount of water would eventually deplete, so then a third loop, a tertiary loop, pulls water in from the river, ocean or lake, and puts it into the second set of water. The three sets of water never physically touch.

There are two types of energy, renewable and nonrenewable. Fossil fuels such as coal and petroleum for example, are a non are-renewable energy. They cannot be recreated once used and they take hundreds of millions of years to form, much longer than the history of humanity. The other less popular methods such as hydropower and solar power on the other hand, are renewable energy. They can produce energy at a constant rate and can be recreated by one way or another. (Micah and Warhol)

Energy is one thing that the manufacturing industry needs to make products. There are two ways they can obtain this energy; renewable energy and non-renewable energy. Non-renewable resources are resources that will not be created again for millions of years, so whatever supply we have now is all we have until we run out. Non-renewable energy also causes pollutants to be put into the environment. Coal and petroleum are the two main sources of non-renewable energy. Coal is formed by crushing organic material with intense heat and pressure over 300 million years of compaction and is burned to create heat energy. About 30 percent the electricity on earth comes from the burning of coal1.

One of the benefits of renewable energy is that it is naturally occurring so does not harm the environment and also that it doesn’t run out. Another benefit is that it is generally it is cheaper to produce renewable energy because created by the environment.

Energy is used for everything we do in life. The two types of energy sources are renewable and nonrenewable. Nonrenewable energy is a source that cannot be used again because it does not renew itself. Renewable energy is a source that can be used again because it can be replenished. There are different sources available for each type of energy. Each resource has its own advantages and disadvantages. Each source has economic and ecological impacts that need to be evaluated.

There are so many forms of energy which are environmentally friendly, the major problem with this sources are its installations and cost (ref). This brings us to wind power, a form of energy which converts wind to energy through wind turbines

Electricity is the gift granted to humans and it is our generation’s duty to use the electricity energy smartly and pass it to future generations. For being able to do so we should cooperate and find ways to save the energy. There are two types of the energy resources: renewable and non-renewable ones. While exhaustible sources of the energy are limited, there are also unlimited sources granted to us by nature. Also according to Chicago Tribune, renewable energy is one of the most important strategies to combat carbon pollution because, unlike natural gas, it emits no global warming emissions (Chicago Tribune, 2012). I would like to give an information about some unlimited energy sources and methods which in my mind are the most beneficial for producing the electricity.

Today, Australian’s are beginning to recognise the dangers that are associated with fossil fuels. Fossil fuels are substances such as coal that are formed within the earth. (Origin Energy, 2015). At present the fossil fuel coal, is supplying 73% of Australia’s energy (Origin Energy , 2015) manly due to its excessive availability, however due to its toxic emissions has made Australia on of the highest green house gas contributors in the world. Renewable energy is sourced from products that can be replenished and are more sustainable for our environment. With Australia’s increasing demand for electricity there are debates that we should be moving towards renewable energy to cut down our annual emissions as well as cut costs on electricity. There are many types of renewable energies that are becoming available in Australia, including solar, tidal, geothermal, wind, nuclear and many more. Some of these energies particularly solar and wind energy could be potential alternatives in supplying Australia with electricity as they are cheap and could reduce our carbon emissions significantly.

Renewable energy resources are our future energy sources and great strides are being made by using these energy applications to improve the environmental impact towards protecting Earth. Hossain, K.A. writes in The Journal of Fundamental Renewable Energy and Applications that there are basically three sources of energy: fossil fuel, nuclear fuel, and renewable fuel sources (Hossain). Fossil fuels are being used up, nuclear fuel must be created, but renewable fuel can be regenerated. Renewable energy includes select natural resources, recyclable materials, alternative fuels, bio refineries, solid biomass, and innovative clean energy (Maczulak). Sources of renewable energy are being used to convert wind, geothermal, hydropower, ocean, biomass, and solar energy into electricity that can be used to power our world. Renewable energy is constantly being replenished (Hossain). “Renewable energy is available in plenty and by far most the cleanest sources of energy available on this planet” (Hossain). Progress is being made in each of the areas of renewable energy to improve it and make it usable and accessible to the general public.

How is the energy source able to produce power? (How it works, are generators/motors used, how does it produce electricity etc. Include images)

Hydroelectricity is another form of electricity that is produced by using water as the resource for generation, this simply means that when water is released (flow), it is aided by gravitational force therefore it generates Kinetic Energy (KE) which is converted into mechanical energy by assistance of turbines and generators which convert the mechanical energy into electrical energy which is then transferred to power lines in that form.

Power plants everywhere generate electricity by converting mechanical power such as the rotation of a turbine into electrical power. In a coal-fired steam station, the combustion of coal turns water into steam and the steam in turn drives turbine generators to produce electricity. Power plants today rely either on fossil fuels, nuclear fission, or renewable sources like hydro.

The current method of energy generation is from burning fossil fuels to generate electricity. However, this method is inefficient because most of the energy invested in burning fossil fuels is converted into heat instead of
