Solar energy is very important now and will be in the future. It is useful alone but may need some help to stay reliable and affordable. Using solar energy to generate power is in a growing phase. It is becoming more and more popular every day. Solar energy systems are ready for more use across the world. Solar energy will help the environment and help people save money. Solar energy helps in many different ways but, there is more out there to catch the flaws that solar has. Solar energy has been used for a while and people need to realize that there are better options than just purely solar; one of these options is better because it has more reliability, a lower cost and a higher rate of energy production. Solar energy works very well; it …show more content…
There are different ways to make it more reliable while staying in alternative energy. These systems are called, “A ‘hybrid’ electric system” (Salkalachen 1250). These are systems that do not work on one source of power they add sources of power. These systems of two or more energy producers are built to make up for the downfalls of the other energy producers in the system. A common system like this is the solar-wind-diesel hybrid system. These systems work in conditions that both would be used but, maybe not at the same time. For example, “Where wind speeds are low at times and when Sun shines brightest and longest, or when the wind is strong but less sunlight is available” (Salkalachen 1250). This says that when one system is not reliable, the other will cover its mistakes. The “engine generator powered by conventional fuels such as diesel” mentioned earlier is to fill any gaps of power when the two systems are at a low (Salkalachen 1250). The diesel power is not reliant on anything that is unreliant and will provide energy for one’s home whether the sun shines or the wind …show more content…
While pure solar systems only use one source of energy, a hybrid grid-connected system uses multiple sources of electricity. While the, “solar electric— or photovoltaic (PV) — systems convert sunlight energy to electricity”, the hybrid system could harvest the wind on that day (Chiras 48). With the multiple systems, a person receives more energy output than a pure solar energy system. This is because that person is producing energy from two resources instead of one. The highest efficiency of solar cells is 28% (Salkalachen 1248). What this means is that for every ray of sun that hits that solar panel, only 28% of it is harvested. Only having 28% of the power is pretty low, so the system could use a wind turbine, which is spun and creates energy to make sure enough energy is provided. With a surplus of energy coming from both systems one could use the benefits of having a grid-connected system. The benefit is that it “‘turns back’ your electricity meter as it is fed back into the grid. If you use more electricity than your system feeds into the grid during a given month, you pay your power provider only for the difference between what you used and what you produced” (Salkalachen 1250). This is saying that when a person is selling that extra energy from that other power source, then a person is saving money on a person’s power bill because the electricity company is paying them for their energy.

Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).
Solar energy products can range from solar panels to cell phone charges, and everything in between. Solar energy is becoming a popular way to fuel homes throughout the United States. All over the country, people are covering their rooftops with solar panels, heating their pools with solar energy, and even turn on the lights in their homes with solar energy. Solar power is quickly becoming America’s most popular form o...
The majority of people look for tax reliefs. Tax benefits by any government are good for the improvement of general public’s lifestyle. Many governments provide lots of support to corporations for solar energy usage in the world. This type of tax benefits motivates to rising electricity generation from solar energy by the residence on their properties to receive more significant tax incentives. "these kinds of methods expand solar usage and reduce production cost due to mass usage " (Wright, 2013). Some state legislatures are now using solar power as an economic and strategic measure to reduce dependence on fossil fuels, the overloaded electrical grid, and foreign energy sources. Solar energy also reduces energy costs, improves efficiency,
Alternative energy sources are renewable, and are most commonly referred to as free energy sources. There are many alternative energy sources such as hydro power, solar power, wind, biomass, and geothermal. Using alternative sources is more expensive in the long run, but it is the much safer option for our environment compared to fossil fuels. Although everything used is completely free, such as water and wind, the equipment used to generate these things is expensive. There are several pros and cons that come with the utilization of alternative energy sources.
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
The solar energy is one of the most important energy on the world because it is totally free, available widely, produces no pollution, no emission, no noise and no carbon footprint. so we must use this energy us can us possible to avoid the effect of other energy .
Diesel Engines- The diesel engine is commonly used with standby generators in industrial or small commercial buildings. They are usually of small rating from few KVA up to 1000KVA and beyond. They are slow speed machines. Larger industrial engines are much heavier and are designed for longer life up to 20-30 years depending on the use. These can be supplied containerised for outdoor locations or can
Solar Energy is an alternative electrical energy source. Its a renewable source, because of its abundant supply and limited environmental impact. Solar energy has the ability to power buildings, electronic devices, and spacecrafts through a specific process. The energy is harvested from the sun to made usable, thus it is a renewable form of energy. Solar energy is created by the use of solar panels, a collection of photovoltaic cells (solar cells, that mean light and electricity). The solar panels have a system in which, it collects the sun’s rays and converts it into energy (similar to the organic process of photosynthesis in plants), and sto...

Solar, wind, and tidal energy is often used in replace of fossil fuels and are most popular because they are renewable. The energy will never run out and can produce a constant energy supply. The energy is also cheaper and more economically sound. The solar, wind, and tidal energy sources are environmentally beneficial because they produce lower carbon levels, does not contribute to the greenhouse effect, and are usually energy saving. However, the alternate energy is not always dependable. It relies upon the weather, and if the required weather isn’t available or produced, there will be no energy made. The energy is also difficult to generate in large quantities. There are not enough facilities, such as wind farms or solar panels, to match up with the developing demand for renewable energy. The large quantities of energy that is produced requires large regions of land for the energy plants to be placed. The plants also have a large capital cost, need to be maintained and require careful planning which is not feasible for many
Regarding solar power, Mistry claims that although the solar power does not generate pollution, it has a lot of costs. Building solar panels with photovoltaic equipment has high costs. For instance, a photovoltaic system for a home can cost around $35,000 (Kumar, 2012). However, if our goal for the future is to create a healthy environment, switching fossil fuels for solar power might be the best choice to achieve that goal. According to Kumar (2012), Solar power is a clean and renewable energy so, it decreases the dependency on fossil fuel and also reduces the air pollution.
Our country has the greatest potential in the world for alternative energy – we have excellent sunshine for solar power and areas of the country that would work well for wind farms. Build new power plants, Minimize electricity theft, Stop corruption and Use renewable energy sources.
Nuclear energy is very efficient and reliable. Unlike wind and solar farms, nuclear power plants can operate twenty-four hours everyday unless subjected to maintenance and can produce a constant energy output that is not affected by weather conditions.
