Alternative energy
Alternative energy is an umbrella term that refers to any source of usable energy intended to replace fuel sources without the undesired consequences of the replaced fuels.
Alternative Energy Solutions for a Brighter Future
In December of 1997, in Kyoto, Japan, an international protocol was adopted by the United Nations that committed industrialized nations to begin making efforts to reduce the level of global greenhouse gas emissions. In February of 2005, the protocol was set into action, thus requiring these countries to develop and incorporate alternative energy sources.
Why Do We Need Alternative Energy Sources?
Currently, the majority of the planet's generated power comes from the burning of fossil fuels like coal and petroleum. While experts agree that the Earth still holds trillions of barrels of oil and nearly a trillion tons of coal, the truth remains - at our current rate, we use these resources 100,000 times faster than they can form. Therefore, simple arithmetic tells us that the demand will eventually overwhelm the supply.
By making the necessary changes to implement more alternative energy sources, we can preserve these valuable resources and reduce the amount of negative ecological effects that are directly caused by them.
Sources of Alternative Energy
Wind Power - Wind power harnesses the power of the wind to produce electrical current. This form of alternative energy is produced by generators attached to the rotating blades of a wind turbine. Wind power is a renewable source of alternative energy that produces no pollution or chemical by-products.
Solar Power - Enough sunlight hits the Earth in one hour to power the entire planet for a year. As an alternative energy source, solar energy from the sun can be collected in cells where it can be converted into electricity. Solar energy can also be used to heat water and as a source of passive light and heat.
Geothermal Heat - The heat that is produced within the Earth is called geothermal heat. The steam that is naturally produced in areas of high geothermal heat can effectively be tapped to propel turbines that will generate electricity without the negative by-products and pollutants caused from fossil fuel burning.
Hydroelectric Energy - The Hoover Dam is one of the most famous hydroelectric energy generators in existence and even though it was the largest when it was built in 1935, today, it is the world's 35th largest hydroelectric power station. One of the oldest forms of alternative energy, water was used to turn water wheels which powered the equipment used at many mills in pre-electricity times.

Alternative Energy - Biofuel from Algae
Algae is the fastest growing plant life, and as an organism it converts sunlight into oil, scientists theorize that Algal biofuel can produce a whopping 30 times more energy per acre than any other biofuel option. The US Department of Energy has estimated that if Algal Biofuel replaced all conventional fuel in the country, it would require 15000 square miles of land to harvest the algae... which is roughly one seventh of the area that is used to harvest corn in the US every year. And a diverse group of byproducts, such as neutraceuticals and feedstocks for producing plastics, can be created in algal biofuel operations, making the production more cost effective. But before we start celebrating the great biofuel solution we've been looking for, there are a few problems... the biomass for producing a significant amount of algal biofuel just doesn't exist yet. The algae has to be grown from scratch and harvesting it is very expensive at this point in time. The potential of Algal Biofuel is staggering... but the problem is that, as of now, it's all just potential. It might be years before the technology catches up to make producing algal biofuel on a large scale possible... but when that time comes, we might be able to finally celebrate a more efficient, renewable, and environmentally friendly energy source.

20% renewable energy by 2020
Raising the share of renewable energy from 8.5% to 20% in the overall energy consumption is a necessary contribution to the global fight against climate change and towards better control over our energy dependence. The various uses of renewable energy are examined: electricity through wind and hydraulic energies; electricity or heat through geothermal and solar energies; electricity, heat, and biofuel coming from biomass. The EU is a world leader in the use and deployment of technologies that exploit renewable energy sources, providing over 350.000 jobs and an annual turn-over of € 30 billion.
