Essentially wind turbines were made first between 500-900 A.D. by the Persians and were used as a water pumping system

Biofuels are made with biomass (biological material from living or recently living organisms) there are many kinds, for example biodiesel involves growing crops that contain large amounts of natural oil, these plants then go through a refining process and subsequently are mixed in with regular diesel to power cars. Bio petrol is made in a similar way; plants are refined to make a natural ethanol.

Alcohol-based biofuels are produced in much the same way as liquor, though, of course with different emphasis. In fact, ethyl alcohol, or ethanol, which is the most commonly used bio-alcohol, is the same type of alcohol that is found in whiskey, vodka, gin, etc.  All of these are based on the fermentation of starches and sugars. The ingredients are gathered, ground up, mixed with water and left to ferment with the help of yeast or other organisms for some period of time (three years for Scotch whiskey!) before it is finally distilled into the final product.

Currently, most hydrogen is made from natural gas through a process known as reforming. Reforming separates hydrogen from hydrocarbons by adding heat. Hydrogen can also be produced from a variety of sources including water and biomass.

Biofuels have been around as long as cars have. At the start of the 20th century

Solar Energy systems are virtually maintenance free and will last for decades.

Biofuels are renewable liquid or gaseous transport fuels derived from biomass (bacterial, plant or animal material).

In open water, waves are generated whenever the wind speed is greater than about 0.5 m/s.

First, let’s clarify where waves come from: sun makes wind and wind makes waves.

Tremendous potential exists for clean energy in waves and tides. Lockheed Martin Mission Systems and Sensors (MS2) is leveraging decades of experience in designing and developing maritime systems into wave and tidal power systems. To do that, we have strategic relationships with key wave and tidal power technology providers. They will provide the technology to convert waves and tides into energy, and MS2 will provide the expertise to help make the systems work in harsh ocean environments and scalable for large-scale production. Wave power generates electricity using special buoys that use the rising and falling of ocean waves to generate electricity. MS2 is partnering with Ocean Power Technologies, Inc. (OPT) and WaveBob LLC to develop their respective wave energy systems for use in future utility-scale power generation projects. MS2 provides its expertise in systems integration, lean manufacturing, and test and optimization analysis to enhance OPT's and Wavebob’s wave power generation technology to utility-scale. Tidal power generating systems use underwater turbines designed to capture the kinetic motion of ebbing and surging ocean tides to produce power. MS2 provides design and manufacturing support to Singapore-based Atlantic Resources Corporation (ARC), which is testing its tidal turbines at the European Marine Energy Centre in Orkney, Scotland. MS2 is also exploring related technologies that can be adapted to shallow and low-rate tidal flows.

idal power can be harnessed using a barrage (dam) built across an estuary that captures the potential energy generated by the change in height (or head) between high and low tides. As the tide goes in and out, the water flows through tunnels in the dam. The ebb and flow are used to either turn a water turbine or compress air through a pipe that then turns a turbine, which generates electricity. Tidal Fences and Turbines Tidal fences and turbines can also be used to capture tidal power. Tidal fences are turbines that operate like giant turnstiles, while tidal turbines are similar to wind turbines. In both cases, electricity is generated when the turbines are turned by the tidal currents that occur in coastal waters. Ocean currents generate relatively more energy than wind (air currents) because ocean water has a higher density than air and therefore applies greater force on the turbines.

Wind power is safe, clean and increasingly affordable – with the potential for production on a much larger scale.Government support is crucial in ensuring the expansion of wind power. We believe such support should be transitional and limited. In the US, there is continuing uncertainty over the renewal of the production tax credit, which provides incentives to invest in wind energy. We are working with other wind energy suppliers to make an effective case for wind energy generation and the renewal of the production tax credit.Wind farms can provide large volumes of electricity (sometimes at a lower cost than conventional power generation)

The U.S. currently produces 9.2 billion gallons of ethanol a year and consumes 9.6 billion gallons.
