The promises of alternative energy

Biomass, geothermal, hydro, wind, solar and nuclear energy are alternative energies we can find in the nature and which are supposed to be infinite. Hydropower is a leading renewable electrical energy source in the U.S. and also the least expensive one there. Solar energy and wind energy are environment-friendly and free sources of renewable energy. There are some companies which also specialize in developing alternative energy technologies (e.g. GE, BP, Royal Dutch Shell) to double their

The venture-funded, privately held start-up companies are the riskiest investments because of their un-proven technologies. In case of the environment, the use of alternative energy is more efficient than using petroleum or other fossil fuels which cause big damage in the economy and ecosys-tems. Alternatives are emissions-free and the cost per kWh decreases with a growing industry of alternative energy. Water, wind and solar energy are non-emissions power sources with no harmful and less waste. But hydro energy for example has disadvantages because the dams have impact on wildlife and water released from dams lead to greater erosion down-stream. Solar energy needs more land if high temperatures are required and also wind en-ergy causes a sterilization of land by windmills. Noises and hazards to wildlife are also negative aspects. Nuclear power plants are very clean and safe. Regarding forecast efficiency we can tell that if changes of the projections are stead-ily going up or down, then it should mean no efficiency. In our case most of the outcome of most of the projected data shows no correlation which would mean efficiency (due to the few data collected), but the changes show the opposite. But regarding the relation between crude oil prices and the projections we can say that the prices affect high or low projections of the capacity or production of alterna-tive energ [...]
