Alternative Energy for Future Nowadays the most common energy resources come from Fossil Fuel‚ which according to research it shows that more of 85% of all energy that is consumed in the United States. It takes millions of years for the Fossil Fuel to actually develop and ready to be used‚ and the main concern of Fossil Fuel is that it cannot be consumed over and over again or reused. Through this analysis it can be assumed that because it takes millions of years for the fossil fuel to develop‚

Alternative Energy Sources Fossil fuels will not last forever. If the human race wishes to continue to live the way we do‚ then we have to look at alternative energy sources such as: geothermal‚ nuclear‚ solar‚ wind‚ and hydroelectric energy. Alternative energy sources are not without faults‚ but along with faults‚ there are benefits and solutions to the issues. Geothermal energy is a well-proven energy resource that can be used to provide both heat and electricity. Geothermal energy is very predictable

1. Minimize Phantom Loads The term “phantom load” refers to the energy that an appliance or electronic device consumes when it is not actually turned on. According to the U.S. Department of Energy (DOE)‚ “In the average home‚ 75 percent of the electricity used to power home electronics is consumed while the products are turned off.” A report from the University of California Berkeley says that phantom loads account for about 6 percent of all national residential electricity consumption. You can

WHAT IS TORQUE? Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis‚ which we will call the pivot point‚ and will label ’O ’. We will call the force ’F ’. The distance from the pivot point to the point where the force acts is called the moment arm‚ and is denoted by ’r ’. Note that this distance‚ ’r ’‚ is also a vector‚ and points from the axis of rotation to the point where the force acts. (Refer to Figure 1 for a pictoral
