Pros And Cons Of Solar Panel

935 Words4 Pages

Before going to what are solar panel and why should one install them, one should have a clear idea of what is solar energy and what is its importance. Solar energy is the light and heat that we get from the sun which is harnessed using different technologies such as solar heating, photovoltaic and solar thermal energy, etc. There are two ways the solar energy can be used, the first is in form of heat and second is in form of light energy. The solar heat is used to produce electricity. Perhaps one of the most useful ways to harness solar energy is in processing water. Large areas which suffer from annual drought conditions use solar energy for treating water. Drinking brackish or polluted water spreads bacteria …show more content…

The answer is if we use renewable energy instead of non-renewable energy, for example instead of using fossils fuels or oil we can use solar energy which will consume the resources. Once the non-renewable resources are gone or finished then they can’t be replenished. Also the fossils fuels create lots of pollution which not affects the people but also to water, fuel, etc. Sun’s energy is immense and is available all day, harnessing that energy can help protect the delicate balance of our environment. Solar energy is not only important for what it can give us but also what it does not do as well. The biggest drawback of processing coal, oil and natural gas and using it is the dangers posed to our natural environment. These energy processes have dangerous side effects as the production and use of this electricity creates …show more content…

Also 10kw of solar panel system will prevent
a) 770kgs of coal from being burned
b) 135kgs of CO^2 being released into the atmosphere
c) 400 litres of water from being consumed. Also one more advantage of solar energy is, it can be harnessed from every part on earth. I know there are places where there is no sunlight but I am talking about places where there is no land (ocean, lake, etc.). Solar panels are more efficiently in this case because they can float of water. Floating solar panel can generate more electricity than ground mount system. There are places where it is built in pond, in Kato city in japan. These plants are anticipated to generated 3300MKW per year. Also it is designed in such way that endures extreme weather such as storms and typhoons.
Disadvantage of solar energy
• Weather depended( in case there is no sun for a week than there will be no electricity)
• Solar energy storage is expensive( batteries are expensive but can store energy and can be used later)
• Uses lot of space( it occupies around 1km on the rooftop)
• Cost of purchasing a solar system is quiet

    A solar panel can be used for many things, but the biggest thing is used for capturing the sun's energy in order to make it useful provide energy to the house, buildings even be sold back to the city or town you live in etc.. It works by collecting the sunlight throughout the day, then converts into energy that's usable, then the electricity travels to the net meter then the energy is used for anything. When having the solar panel on a roof you can use it for personal use or even sell it back to the electrical company and they’ll pay you. There are about 73,000 terawatts of energy shining down that's 10,000 times then what we use on daily bases. Perks of having solar panels it's a tax 30% tax write off, doesn’t need any fuel combustion, Securing your energy and not depending on National

    Energy is a key factor in today's society, especially in Kentucky. Kentucky's main energy resource is coal, 91.8 percent of our energy comes from this resource but coal is nonrenewable, meaning that there is a limited amount of this type of fuel. Coal mining is also detrimental to the environment, people living and working in coal mining communities have a higher chance of getting lung cancer. with surface mining, this has been linked as a cause for poisoning local residences from the chemicals used in the mountaintop mining. there are still issues with the environment and natural wildlife in the surrounding areas of the coal mining as well.

Instead of having a gas tank and having to fill it up at a gas station, these cars have batteries in their place and can be recharged with a larger charging station and needs 220 volts. The recharged batteries stay charged until the car is driven. Some people say that battery powered cars are slower, but it isn’t by much and battery powered cars think is worth slowing down a little if it means saving the planet.

    wind energy and solar energy are both renewable types of energy they create no pollution and are fully sustainable as they are both powered by natural sources and if there is no wind one day the solar panels can generate energy and if it 's cloudy another day the windmills can generate energy also the energy created during the summer can be sold to the grid for extra capital that can be used for field trips, renovations, etc. Geothermal heating systems are rated the most efficient and eco-friendly heating systems. The system works using buried coils that contain a liquid, typically a mix of water and antifreeze. The liquid is warmed to the same temperature as the earth and then runs through to the home where a compressor extracts the heat but not only that geothermal heating requires no fossil fuels so it is very eco-friendly LED lighting is an efficient and eco friendly lighting alternative because they waste much less energy in converting to light compare to incandescent lights which waste 90% of the energy to convert to heat not only that LED lights last up to 15-25 times longer that traditional light bulbs this makes LED a much better source of lights than others because it wastes less energy and it is more efficient at doing its job this is so much better for the environment because it uses less energy that other lighting sources

    Instead of burning fossil fuels that will be depleted within short generation, alternative energies such as the wind turbine or solar panels needs to be implemented to sustain and care for the resources that remain. The concept of reducing our Carbon footprint in the world is the more modern way of looking at sustainable living, in which the World realises humans have not used resources wisely. By looking at the changes over the past centuries, an International network of scientists have unanimously concluded that human society is altering natural functions in three fundamental ways. And consequently, they were able to define four basic conditions that must be met if we want to maintain the environmental services that sustain human society.

    2.1 INTRODUCTION Non-Renewable Resources are resources that have the potential to be used up due to consumption or overuse, they have production, development or replenishment rate that cannot match up with the depletion rate. In short these are resources that can be finished, output exceeds input, and they are infinite. Non-Renewable resources vary from non-renewable fossil fuels like coal, natural gas and oil, non-renewable alternative energy sources like nuclear energy and deep-earth geo-thermal energy, soil, and minerals (Botkin & Keller, 2012). These non-renewable resources range from a few years, up to thousands of years to replenish. The local as well as global challenge, is that most non-renewable resources are directly exploited by humans and their existence is widely threatened were usage

This is for a few reasons, firstly we are so reliant of them that it will be impossible to completely change to renewables overnight . fossil fuels are still the cheapest form of energy available so why would individual people and business chose otherwise to put money into renewable research,, well governments around world have realised the danger of global warming and they know an overnight switch is impossible so the have implemented taxes on fossil fuels and inefficient use of them and put this money into renewable energy research, also provided grants and tax breaks for people and business that are switching to renewables. these actions will slowly make renewable energy more cost effective and appealing to everyone and will move the world away from fossil fuels and towards renewable green energy sources. Similarly with stem cell research i think the potential medical benefits of mastering stem cell therapies is just too big.
