Using the calculator is quite simple. At the front page, put in your zip code. You will be sent to a page to enter some basic information about your home, such as the date that it was built, the amount of livable square footage, and the types of energy used. After filling out the appropriate slots on that page, click Save Answers. This will take you to another page that has links to various aspects about a home, such as water heater, lighting, etc. The calculator will also assign you a Session ID number, which you should write down on the activity sheet (the number is found next to the Calculate button). Clicking on each on of these factor links will allow you to personalize the information about your home, such as what type of air conditioner you have and what are your temperature settings. After you have visited a link, the page will place a blue dot by that link to tell you that you have already filled in that information.
Another disadvantage of renewable energy sources is the reliability of supply. Renewable energy often relies on the weather for its source of power. Hydro generators need rain to fill dams to supply flowing water. Wind turbines need wind to turn the blades, and solar collectors need clear skies and sunshine to collect heat and make electricity. When these resources are unavailable so is the capacity to make energy from them. This can be unpredictable and inconsistent. The current cost of renewable energy technology is also far in excess of traditional fossil fuel generation. This is because it is a new technology and as such has extremely large capital cost.
Renewable energy facilities generally require less maintenance than traditional generators. Their fuel being derived from natural and available resources reduces the costs of operation.
You will notice that water, wind, sun and biomass (vegetation) are all available naturally and were not formed. The others do not exist by themselves, they were formed. Renewable energy resources are always available to be tapped, and will not run out. This is why some people call it Green Energy.
When its source cannot run out (like the sun) or can easily be replaced (like wood, as we can plant trees to use for energy)
When their sources are carbon neutral. This means they do not produce Carbon compounds (such as other greenhouse gases).
When they do not the environment (air, land or water)
Renewable energy includes , , , and sources. Renewable energy can be converted to electricity, which is stored and transported to our homes for use. In this lesson, we shall take a closer look at how renewable energy is converted into electricity.
Welcome and Have fun.
