1 What is the potential energy of the water in a lake of surface area 10 square kilometers, with an average depth of 15 m, and elevation above the electrical generator of 200 m? (Note that you can ignore 15 m depth of the water compared to the 200 m elevation, i.e., use the total mass of the lake at an elevation of 200 m. Also, a cubic meter, i.e., 1 m3, has a mass of 1000 kg. The wonders of the metric system!
Solar power in Canada is gaining attention to many people. You will be informed about what solar energy is and how it works, the environmental impacts of solar energy, why you should care about it and what you and others can do to help promote it. You will have a better understanding of solar energy and why you should take the switch.
There is physics involved in these wind turbines as they change wind into mechanical energy and then into electricity. The energy produced depends on the volume of the air, the density, and the wind speed. The mass per unit time is the mass times the density times the wind speed or m = mass, p = density, A = area, and v = wind speed; m = pAV. Because the function of the wind turbine is to transform the wind’s kinetic energy into electricity the equation for kinetic energy is needed; KE = ½ mv2 or kinetic energy equals one half the mass times the velocity squared. Then, using substitution, the power in the wind depends on the density of the air, area swept out by rotors, and the cube of the velocity or ½ pAV3. Using Betz’ law the theoretical energy model for extracting 59% of the energy is power = 16/27(½ pAV3) .
He then started to explore on his own how generators worked and how this could be used to operate a radio. He read about how the wind could be used to power a wind turbine, and decided to make one. In 2000, there was so much rain that it flooded, sweeping away the seeds. This disaster diminished yield, which meant less money and lack of food for people. This eventually became a famine. To make things worse, William didn’t have enough money to pay fees to go to school, which meant he had to drop out. However, he continued his education by going the library, where he learned about generators, wind turbines, and electricity. He said that he knew that “if windmills existed on the cover of that book, it meant another person had built them.” He was confident he could build one. When he was seen, people mocked him and called him a “madman with his garbage,” or “just a lazy boy who plays with toys.” Despite the insults, William eventually finished his wind turbine. When he finished the wind turbine, William made it light up a lightbulb, and eventually his entire house. William reflects on his experience that “If you want to make it, all you have to do is

Wind turbines can be very useful in bringing energy into your home. They are especially useful when solar panels aren't working. They take the wind speed from oceans, lakes, dugouts, or rivers and turn it into energy. To use the wind turbines most efficiently you should set up a wind power system.
Claim: Solar power has the potential to become the United States main supply of energy and replace are needs for more conventional and harmful forms of power generation.
...sidered as a viable alternative energy source at the present, nonetheless if, with further research, efficiency continues to increase and the cost to produce solar panels continues to decrease, solar energy could be a major contributor to power in the future.
Although solar seems to be excluded from most of the disadvantages listed above tied to using renewable energy sources, it still has two big main disadvantages. The first being that, it is impossible to shut off. The fact that there is no way to shut these solar panels off makes them prone to catch fire. This is harmful to the place they are located. It is especially bad when people put them on their roofs which can cause house fires. Another big issue with solar is that it takes a lot of room for the amount of energy that it produces. According to the U.S. Energy Information Association to produce 1 MW of solar energy, assuming that your panels are located in price sunny locations, it takes 7.4 acres of solar panels. When you compare it to the nuclear reactors that produce on average 770MW for approximately 500 acres of land. To produce the same amount of energy as one single nuclear reactor you would need approximately 5698 acres of land which is 11 times the amount of space that nuclear
In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these. As a world, we are dependant on dwindling fossil fuel supplies and take for granted electricity, oil, and gas. There are four completely renewable sources of energy around us that should be used and developed, they are: wind, growing plants, flowing water, and the sun. These sources of energy are the ones we should be tapping, because they are reliable and renewable. Harnessing the suns energy is the most certain and ultimate energy source. Looking at a brief history and some facts about solar energy, a glimpse of the future can be seen, a future not dependant on fossil fuels.
The sun has been a major aspect of life since the beginning of time. People used many other forms of energy before electricity was discovered. There has been a debate over energy resources for years. Many people are worried about what current energy resources may be doing to the environment. Oil spills and nuclear power plant mishaps have only been a few accidents that have had a big impact on the environment and the people who inhabit it. There are plenty of energy sources that do not harm the environment and are still able to get the job done. Solar energy is one energy alternative that will insure the betterment of the country and, at the same time, protect the natural environment.
I have already written about the obvious benefits of going solar. There are other benefits as well that decrease the impact on our earth over time. Solar panels and battery banks have a life of 25-35 years and don't need anything more than general cleaning, snow removal and monthly water filling. Solar energy is the cleanest and purest form of energy, allowing for cleaner air overall in our environment. There is great hope for a lot more solar panels to be installed worldwide.

I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free and healthy power? It is evident that solar energy is a healthy source of energy, which will help stop global warming all together, but it is economically efficient to switch everything to solar energy. Solar energy is capable of becoming the world's future power supply because, it is renewable, eco-friendly, and extremely efficient when strategically placed.
First of all, solar energy is the energy produced when the sun heats the solar panel. Thus, when the sun heats the panels, it produces electricity. Solar power produces energy during the day and can store energy for the night. Solar power does not pollute the environment. However, it has high maintenance cost, and it takes a lot of land space.
