speech writing on solar energy good or bad
Answers
Topic: Solar Energy
General Purpose: To inform
Specific Purpose:To inform the uses of Solar Energy to my audience.
Thesis:When all of our natural fossil fuels are low or gone, solar energy will be one of the leading sources of energy that we will need in the future. Introduction
Attention Getter: Natural fossil fuels, such as coal used for burning, oil used for gasoline, and natural gas used to heat and warm houses, are a threat to the Earth and everything in it. Fossil fuels pollute the air and they are non-renewable and non-recyclable. We need different energy sources that are renewable and recyclable for our future existence. Unlike fossil fuels, solar energy is renewable and recyclable. When all of our natural fossil fuels are scare or gone, solar energy will be one of the leading sources of energy that we will need in the future. With all of the technology we have today, we can develop different ways to use and harness these energy sources. Reason to Listen:Solar energy is making a big impact on lives today all over the world. The development of solar energy in all ways and technologies is making our world a cleaner, safer, and less dependent nation.
A. Thesis Statement: When all of our natural fossil fuels are low or gone, solar energy will be one of the leading sources of energy that we will need in the future. B. Credibility Statement:
My dad is an electrician that puts up solar energy plants for businesses. I had to research for this paper.
C. Preview of Main Points:
1. First I will explain solar energy technology and how it can be used in houses.
2. Next, I will explain the uses of solar energy and how it will be helpful saving water.
3. Finally, I will explain the unique uses of solar energy in transportation and military weapons. II. Body
A. People have created new technologies for others to use in their homes, vehicles or buildings. 1. One of the technologies that people have created to be energy efficient is the photovoltaic cells or “solar cells” which use sunlight and convert it into electricity automatically. PVs can be used in anything from watches to an electric grid. They can also be used to provide energy to places where power lines cannot be attached to buildings. “Thermal technologies use the heat from the sun and use it directly in space or water heating in homes and buildings or it is directly converted into electricity,” says Fischer and Finnell. Thermal technologies are also used for agriculture needs that farmer’s livestock or crops require. With solar energy being used in electrical, heating, and transportation applications, the idea for an energy efficient house would be more probable. Energy efficient improvements can cut energy costs by over 40% in most affordable housing. They help reduce health risks from mold, dust mites, radon, and combustion by-products and other contaminants. These houses have less condensation, and better moisture control and temperature. These energy improvements usually cost less than the savings they offer on utility bills. Increasing the value of a home is a great investment-paying high energybills are not.
