Wind energy is another renewable source of energy that could be a potential alternative energy source. “Wind power is the conversion of wind energy into a useful form of energy such as using: wind turbines to make electrical power, windmills for mechanical

As the Law of Conservation states, energy can be neither created nor destroyed (The Secret Lives of Energy). That means that an energy source has to be use in order to generate the energy needed. It is common knowledge that the pollution caused by the use of fossil fuels over time is making society live in a contaminated world. In addition, the cost of the use of fossil fuels is increasing and becoming too expensive, forcing people to find alternate ways in which they can pay less for the use of energy. The use of fossil fuels over time has increased to a point where the remaining reservoirs have decreased by a large margin. On the other hand, renewable energy is

These alternatives can be helpful in reducing carbon emissions while ensuring the energy independence . These sources are wind ,solar ,geothermal, hydro, nuclear and renewable bio fuels. Some of these sources are renewable , meaning they can be replenished, while others like nuclear, are non-renewable, yet are clean sources of energy. For better sustainability , society continues to explore the challenges of these energy options to help implement the necessary changes for an environmentally friendly and energy independent future.

Power production can come from multitude of sources with different types of power plant facilities each with some sort of unique need; these sources include coal, natural gas, nuclear, wind, water also known as hydroelectric, solar, geothermal and biomass (U.S. Energy Information Administration). These energy sources are broken down into one of two categories, renewable or nonrenewable.

In just one hour, the earth receives more energy from the sun than the entire world uses during a whole year.

An important role of them is to generate energy from natural resources, for instance solar thermal. It is a solar water heater that uses the power of the sun to heat water thus reducing the amount of gas or electricity required. In fact, according to Education Scotland, solar power plants in Spain have generated 3 gigawatts of power which represents 2.8% of Spain’s energy needs (Solar – Renewable Energy, 2016). There are many renewable energy technologies that can prevent acid rain, urban smog, pollution and the burning of coal. Canada has improve on its uses of fossil fuel, the uses of renewable energy grew from 2% to 11% (Healing, 2016). Therefore, if using renewable energy sources will give us the luxurious of being able to have electricity, heat our homes, transport, and protect the environment, then why not use it.

What exactly is renewable energy? In the terms of The Natural Resources Defense Council (NRDC, 2015), renewable energy comes from sources that can be replenished easily. Solar power, wind energy, hydroelectricity, geothermal, and biomass energy are all examples of this. All of these sources can be replenished, or renewed naturally. Wind energy is free of pollution and costs about the same as electricity from coal. Solar energy is growing cheaper, and is used in many every day appliances. Biomass energy uses materials such as wood, corn, soy, and sometimes animal waste. It takes time for biomass energy to grow, but it is a critical renewable resource. Hydroelectricity is energy produced by flowing water and accounts for six percent of America’s electric supply (NRDC, 2015). If we can make the transition to a future of cleaner energy sources, we can eliminate our dependence on fossil

Renewable energy is an extremely popular topic in conversation, politics, and media. Consumers are interested because it raises real estate value, cuts power bills, and offers a tax break on homes equipped with solar panels. Environmentalists agree with renewable energy because it produces little or no waste products such as carbon dioxide and other chemical

Renewable energy sources are good for the environment but some people frown upon the idea of having renewable energy sources. They are more expensive than fossil fuels and nonrenewable energy sources. A Lot of energy needs to be put in both the research and manufacturing of nonrenewable resources. Renewable energy sources are cheaper because of the energy source already having the components in order

Renewable energy may seem like a daunting task, but the benefits to humanity could be incredible. Public uses of renewable energy range from transportation all the way to heating and cooling. Everything we use could become less explosive and less expensive. Cities with a high concentration of people could become safer and healthier places to live. Transportation could be converted to electricity dramatically, improving smog conditions. Global warming may or may not

Renewable resources are also known as alternative energy sources. Alternative Energy is any source of energy that can be renewed (Issit). Renewable Energies include hydrogen fuel, biomass fuel, hydropower, solar power, geothermic energy, and nuclear power. Hydrogen fuel is an amalgamation of hydrogen and oxygen which is used to produce electricity (Issit). Biomass fuel is made from materials which have already been used, such as compost, and can be used to generate electricity (Issit). Hydropower can be created through moving water or wind to generate electricity (Issit). Using sunlight to produce electricity is called solar power (Issit). Geothermic energy is energy made by the heat under the earth’s mantle (Issit). Nuclear power is

Renewable energy is derived from sources that are naturally replenish-able and supply of energy from these sources is infinite. The main purposes served by using renewable energy are many such as generation of power, transport fuel production, and for heating of houses and other living places. Except the naturally occurring main difference of supply source between renewable and non-renewable energy, there are several industry related differences as well. Usability of renewable energy, level of Greenhouse Gas (GHG) emissions, cost of generating energy, and the phase from renewable energy production is passing through, all these industry related aspects for both renewable and non-renewable energy are different.

Renewable resources are an energy source that is able to be constantly used without running out of it. There are many renewable energy sources, such as wind, solar, hydropower, geothermal, and tidal. The only exception to this list is nuclear, which is non-renewable, but somewhat eco-friendly. Wind energy is harnessed when wind is used to turn blades on a wind turbine, the spinning of the blades also spins a generator inside of the wind turbine that creates energy. Advantages of wind energy is that it’s eco-friendly, creates no emission of harmful gases, inexpensive to build, and starts up fairly quickly. The disadvantages of wind energy are that it needs wind, when there are days of no wind, then electricity cannot be produced. Another disadvantage is that the noise can affect the wildlife, and it could possibly harm wildlife with its blades swinging around. Also, it has to be in a place where it won’t distract a person’s vision and to match the energy production of a small thermal power station, you need many wind turbines. Another energy source is solar energy. Solar energy is produced by the sun’s rays. A solar panel is made up of many solar cells made up of silicon, these are also called photovoltaic cells. The cells work like this, first the sun has

Renewable energy is energy or power that is created from natural resources such as wind power, oceanic waves, and the sun. These resources can be used to replace other energy generators such as electricity and gasoline.

These energy sources are renewable since they are derived from replenish able sources. Electricity is produced using hydroelectric power. This is the use of water that is turned into electricity as it is put through a turbine. As long as there is an adequate supply of water, the electricity supply will be available. The fuel that I use to operate my car also comes from a renewable source since the earth replenishes the materials used to produce fuel and natural gas. The constant consumption, however, may lead to a shortage of materials in the long run, because these natural components need time to replenish themselves.
