Wind is a clean source of renewable energy that produces no air or water pollution.

Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unevenly heats the surface of the Earth. As hot air rises, cooler air moves in to fill the void. As long as the sun shines, the wind will blow. And as long as the wind blows, people will harness it to power their lives.

The wind spins the blades, which turn a shaft connected to a generator that produces electricity. Other turbines work the same way, but the turbine is on a vertical axis and the blades look like a giant egg beater.

First generation biofuel are those fuel derived from vegetable or animal fats/oils, starch or sugar with the use of modern technology. 1. Let the base organic material (corn, sugarcane, wheat, etc) pass through a grinding meal to pulverize the selected material. 2. Then, liquefy it by placing the blend of water, grain powder and an enzyme that facilitates the breakdown of the grain compound into a high-heat cooker. 3. Cool it afterwards. Add another enzyme that will facilitate the conversion of starch into sugars which are then fermented, producing alcohol from the cooled mash. 4. Start the fermentation by adding yeast to the sugar mixture. The sugars will be broken down to ethanol (a form of alcohol) and carbon dioxide. 5. Distill the fermented mixture in order for the ethanol to separate from the solids. 6. Get rid of the water from the separated ethanol through a dehydration process.

More than 70% of Earth's surface is covered by oceans which contain two types of energy: mechanical energy from waves and tides and Thermal energy from solar radiations falling on the ocean surface making them the world's largest solar collectors

The Transesterification process is the reaction of a triglyceride (fat/oil) with an alcohol to form esters and glycerol

The water that creates the energy ultimately returns to the Earth, where it can be used again.

When sunlight strikes a solar cell, electrons are knocked loose. They move toward the treated front surface. An electron imbalance is created between the front and the back. When a connector, like a wire, joins the two surfaces a current of electricity occurs between the negative and positive sides

Wave energy is about using the energy of ocean waves for producing electrical current. It is a renewable energy resource and often confused with Tidal Power.

Wave energy is considered a form of hydropower, although it is the wind blowing over the surface of the ocean causing waves. So in many ways, wave energy is also wind energy - with all the pros and cons.

Sea waves have associated a form of renewable energy which can be captured by using a hydro mechanical device that in turn drives an electrical generator to produce electrical energy.

A benefit is very little pollution. However, there is a very serious potential draw back. It can be very hard of fish populations. The proposal for tidal power is to put turbines on the bottom of a bay and let the water rushing in and out with the tide turn them and generate electricity. However, along with the water will come fish and other marine animals. What do you think will happen when these critters get sucked into the turbines. Can you say sushi, boys and girls? Putting some kind of screen in front of the turbine to prevent this would just mean that the animals would be sucked up against the screens, obstructing the flow of water through the turbines.

The World Energy Council has estimated that approximately 2 terawatts (2 million megawatts), about double current world electricity production, could be produced from the oceans via wave power.

Wave energy is generally considered to be the most concentrated and least variable form of renewable energy. It is the high power density of wave energy that suggests it has the capacity to become the lowest cost renewable energy source.

Wave energy is a renewable, zero emission source of power
