Compare And Contrast Renewable And Solar Energy

Good Essays
Around the world are many different energy sources. There are two main types: renewable and nonrenewable. Renewable sources are sources we can use repeatedly without fear of running out. Some examples are water, solar, and wind. Nonrenewable have a short shelf life. They are slowly running out. Examples of these are coal, natural gas, and petroleum. The two I will be comparing are ethanol from corn and solar energy from the sun. Solar energy is self-explanatory. We harness the power of the sun for energy. Solar panels can be put on cars, calculators, houses, and space crafts. The sunlight hits the cell, loosens the electrons, and turns it into electricity. Because of emerging technology, the energy from the sunlight can be stored on a battery. This makes it sustainable and easy to use (Solar Energy, n.d.). Ethanol from corn is a renewable source of …show more content…
Solar energy will always be able to use the sun for power. It won’t leave any pollutant and, unlike wind, it can be used almost all the time. The downfall is that you can only get energy during the day unless you have a battery (Solar Energy, n.d.) . Installing solar panels is also very expensive, however, one would save quite a lot of money on their energy bill with solar panels. Solar panels require a lot of space to collect energy. Ethanol is a renewable source of energy, but it is not very sustainable because it needs to use nonrenewable energy to be produced. However, Econetwork says that, “The amount of fossil fuel used compared to the amount of solar energy captured by the ethanol feedstocks is referred to as the net energy balance.” It may balance out, but we won’t be able to make ethanol once we run out of fossil fuels. Ethanol would also be considered sustainable because it uses corn, one of the most widely used plants in the U.S. Both types of energy have their pros and cons, but all in all, they are quite

    Solar energy is renewable source, which means we can never run out of the sunshine. Due to which, utilizing energy from the natural renewable sources like the sun, dependence on sources such as oil and coal that are harmful to environment can be decreased. As shown in figure 2, the solar energy is a renewable energy source. Although, energy that is produced from other sources like coal and natural gas are expensive as well as they are not renewable. Moreover, people have been able to capture some of the sun’s energy that falls to earth and convert it into usable power for a variety of practical uses such as for cooking, heating, and to power everyday appliances.…

    We will be discussing these in detail later, along with biomass. Let’s start with discussing solar power. Solar power is power from the sun. We can use this energy for many things, including warming water, making electricity, and heating homes. Solar energy is good because it is clean and renewable energy.…

    Solar energy is the future. Solar energy is where the earth receives from the sun primarily as visible light and other forms of electromagnetic radiation. It has many benefits. In solar energy we can get energy that is clean and not harmful for our environment. It requires sun and is needed to be placed in an appropriate spot in order to function properly.…

    That charged energy is sent to a central receiver, or solar tower located in open fields (Union of Concerned Scientists 38). The second factor to make the system work happens at the central receivers or solar towers, located in fields. The towers have the similar mirror panels, called heliostats, that are found on the roofs of the houses. Their job is to receive and change the sunlight to thermal energy, which is powered by a generator (Union of Concerned Scientists 40). The last piece that completes the solar energy process requires a parabolic dish, which uses a saucer to collect the energy ( ) on top of buildings or houses.…

    They have many similarities and differences, but solar power is is still a better source. Both Nuclear and Solar are power sources for humans, but solar power is more convenient that nuclear. There is a cost to build both nuclear power plants and solar power farms, but solar power plants cost a lot more. However, the cost of the fuel for nuclear power (uranium) is expensive while the cost of the fuel for solar power is free. Both solar power and nuclear…

    This area is where breakthroughs in the science and technology of solar cell materials can supply the greatest effect on the cost and great implementation of sun electricity (LEWIS 799.) A key problem is material purity. Present day solar mobile designs require high-purity, and consequently costly materials, because impurities block the flow of electric charge. That problem might be diminished if the electric charges needed to travel simplest a short distance, through a skinny layer of material. But skinny layers could not soak up as plenty sunlight to begin with.…

    First off, one benefit from using solar power is that the use of it does not change the basic energy balance of the biosphere because the solar energy converts to heat energy which is absorbed by the atmosphere. The Sun delivers 10,000 times the energy used by humans (Wright and Boorse 395). Solar facilities can become operational within months of the decision to build them unlike new nuclear and coal power plants (Wright and Boorse 400). Also, these facilities do not have to predict what the energy demand will be far into the future because it can add energy capacity as needed; allowing investors an opportunity to invest smaller and less risky amounts of money. This makes investments in solar power much more appealing due to low risk and quick rewards.…

    CONVERSION OF SOLAR ENERGY FOR USE Producing solar power is just as simple as using the sunlight that heats the surface of the earth. Now, more than ever, it has become an important alternate energy source. It can be used in two different ways, as a heating source and as an energy source. It can generate heat, lighting and electricity. Understanding how this important energy source is produced is just the beginning.…
