Energy Alternatives: * Alternative energy is any energy source that is an alternative to fossil fuel. In a general sense in contemporary society‚ alternative energy is that which is produced without the undesirable consequences of the burning of fossil fuels‚ such as high carbon dioxide emissions‚ which is considered to be the major contributing factor of global warming. * This chapter discussed only a few of the possible alternatives to our current combustible energy generation system

NUCLEAR ENERGY Nuclear energy is the energy contained in the centre ‚ or nucleus of an atom. The nucleus is the most powerful source of energy that exist. Nuclear energy is use in scientific research and in medicine treatments. It powers satellites and submarines‚ and it is used to produce electricity. People have also put nuclear energy to destructive uses through the creation of weapons.1 Nuclear energy also called ATOMIC ENERGY‚ energy

Water has easily fufilled our every need in many ways. As we near the twentyfirst century‚ a time when public attention is focused on the environment and society is increasing at an ever accelerating rate‚ the energy crisis continues to burden us.

Geothermal energy What is geothermal energy‚ and how can we use it in society? Geothermal energy is the use of the Earths very own energy. It’s renewable‚ clean and can range to easily acquirable hot springs on the surface or hot rock found a few miles below the surface. Or you can go a bit deeper and hit the extremities of the molten rock (magma). In the US around 80% of all geothermal hotspots are found on the western states i.e. Alaska and Hawaii. Wells are drilled deep into the underground

Energy Debate The use and costs of energy in the United States has been a debate that has been going on for many years and will only continue to go on for more. People believe that decreasing dependency on oil and using alternative sources will be a solution to the many problems we face. The costs are high to do the switch‚ but may pay for its self in the long run. This debate may never be solved because everyone has a different opinion. I feel as though both sides have valid viewpoints. I believe
