Renewable Energy : Fossil Fuels

Solar energy is a renewable energy source meaning that the energy is generated by the sun. The way that solar produces energy is by the sun's rays that reach earth and converts into heat and electricity. Its transported by photovoltaic ( pv devices ) and solar thermal electric power plants. Examples of this energy source is : solar powered window blinds, bulbs, refrigerators, radios, calculators,

The sun, wind, and water are just some of the natural resources that people were able to use to make energy. There are solar panels, wind and water turbines that harvest the energy within these elements and converts them into electricity. These new technologies could potentially solve some pollution problems that have arisen over the years. First, look at how a solar panel is able to convert sun energy to electricity. Every single day, the sun rises over the horizon shining its rays over the land. Solar panels convert photons from the sunlight into direct current electricity. This electricity is

There are many types of alternative energy that are available and being used. One of these sources is solar power. Solar power is the fastest growing and most popular source of alternative energy. There are two processes of solar power that each depend on the nuclear fusion power from the core of the sun. The first process of solar power involves solar cells that depend on the photovoltaic effect to absorb photons and turn them into electrons. The other process involves mirrors or lenses that concentrate a large area of sunlight, or solar thermal energy onto a small area (Williams,"What Are the Different"). Solar power is used to generate light, heat homes, generate electricity, and used for air conditioning in

Abstract – The world can’t be imagined without IC Engines ,as their applications are wider in various fields. And mainly used input for this engines are fossil fuels. But the challenge in this is decreasing rate of resources. The fossil fuels may not be available after some years if they used in the same way .Not only the fossil but also the electric power is the non renewable energy, This paper concentrates to run the engine without fossil fuels or electricity.

As a evergrowing country, we need reliable energy resources. We need sources that wouldn’t require a large plant, cause environmental effects, be cheap enough to afford, would be something that is easily replenished, and something that would be safe to use. For example, burning coal (a nonrenewable source) is not good for the environment. We are suffering consequences such as more holes in the Ozone layer from using more than needed fossil fuels. Pollution is also a highly equal problem we are facing.

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

There are many different types of renewable sources such as solar panels, wind turbines and hydroelectric power. Solar panels work by using sunlight and enhancing it into electricity which is then distributed. They work when the sunlight hits the anti-reflective coating of a solar panel which creates a charge with the delocalised electrons in specially treated semiconductor material. These were first created in 1954 by Bell Laboratories . Although it was very expensive at the time of discovery, over the years the price of manufacturing and installing the solar panels have decreased while the efficiency of the panels has also decreased meaning more energy can be produced at a faster rate. Another type of renewable energy which is very popular is wind energy produced by turbines. This produce energy by using the

Wind Power – Wind energy is another one of those renewable sources that is very, very environmentally friendly, and actually has been used for quite some time. Generating electricity from wind is pretty straight forward – basically, electricity is produced when wind blows a massive turbine that spins to create the

Solar energy is the energy from the sun. It uses sunlight to produce electricity. These panels are usually installed on the roof and positioned to face the sun. Most countries all around the world use solar energy to reduce their dependence on fossil fuels and making it as a sizable share of their energy supply. Solar panels are used in large numbers by homes and offices to reduce their monthly electricity bills and reduces the need of electricity from utility companies.

The use of solar power is currently gaining popularity in various areas and fields. Typically the solar energy is captured and then converted into electricity through photovoltaic cells. There are various areas that currently use solar power these include; in water pumping, this is commonly used in developing countries where the solar energy is harnessed and used in pumping water in remote areas. The solar energy is also used to power off-grid desalination plants. Solar power is increasingly being used in the production of electricity for homes, schools and businesses. Another current use of solar power is in industries where it has been used to power TV and radio repeater stations. Solar power is also being used in residential homes as a source of heat. They use solar energy to heat water supplies and also swimming pools. There is also an increase in use of solar power in public transportation vehicles like trolleys, busses and light trains. There are also future plans for solar powered bus shelters development. Small gadgets like calculators and watches also use solar power since they require little energy (Anderson, 2012).

Our society today thrives off of energy consumption in order to carry out daily activities. Since the second and third centuries people have been using fossil fuel for heat and energy. In the 1700s, the use for coal really took off when it was found out that it could be used as a source of energy to create the energy needed to drive locomotives. As each new invention that needed power came into existence since the 1700s, fossil fuels became the energy source that was chosen and because of this our society has become dependent on fossil fuels for energy (United States Department of Energy, 2013). Today fossil fuels are still in high demand.

One of the greenest forms of energy developed by technology is solar energy. Generally speaking, it is the energy taken by the sun and converted into a power source that is usable in everyday life. The United States Department of Energy defines solar energy as: “Electromagnetic energy transmitted from the sun (solar radiation). The amount that reaches the earth is equal to one billionth of total solar energy generated, or the equivalent of about 420 trillion kilowatt-hours” (Department of Energy S). This energy is gained by solar panels that collect energy from the sun. Panels can be used for power in almost any structure, from a handheld calculator to solar-powered homes and cars. Solar energy is very useful, albeit that it does have negative effects. For example, you cannot use solar energy all the time. It is only available when the sun is visible from the sky, and cannot be seen at times such as in bad weather, or at night.

Since the industrial age, fossil fuels have been used as a source of energy and power. The fossil fuels are used and converted into coal, oils, and gasses. The products of fossil fuels are mostly Carbon, which is harmful to the environment, leading to global warming and climate change, and O-zone destruction. These conditions cause global temperature increase, ocean acidification, rising sea-levels, health problems due to pollution, and the destruction of ecosystems (climate.nasa.gov). Considering these issues, alternative energy sources are something that can be used to help combat harmful fossil fuels and lessen humanity’s Carbon footprint (the amount of carbon dioxide and other carbon compounds emitted due to the consumption of fossil fuels by a person, group, etc.).

Finding energy sources is an issue that polarizes scientists, politicians and citizens alike. The most critical points of this debate are at fossil fuels and renewable energy. Energy efficiency is arguably the most dire concern facing the planet, because it significantly impacts all areas of everyday life. Common ground can be found in this controversy because both parties do agree that humans have a responsibility to future generations. That responsibility is to preserve the resources of the Earth, while offering this generation energy that is affordable and accessible.

Solar energy is the conversion of power from the sun to usable electricity (Alternative Energy, 2014). The most common source of solar energy utilizes photovoltaic cells to convert sunlight into electricity (Alternative Energy, 2014). Photovoltaics use a semi-conductor to absorb the radiation from the sun, creating and emitting electrons, which are then harnessed and used as electricity (Alternative Energy, 2014).
