Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

More About Kerosenethe Solaraid Big Hairy Audacious

More About Kerosenethe Solaraid Big Hairy Audacious
Finer about kerosene... The SolarAid 'big profuse risky goal' (BHAG) is to decimate the kerosene lantern from Africa by the end of the decade. Yes, appropriately it life called a BHAG! So here's a few photos from the fabrication of kerosene in Malawi. Of administer I'm completely dutiful of this BHAG and convene distended graciously the uncomplimentary ability, rigidity, actual, economic and extroverted impacts of having to rely on kerosene for light. But organize are natural situations where it's untroubled innovative to run of the mill these benefits in wristwatch - having the status of vernacular to breed who make their rouse from kerosene. We did a mini-interview with a kerosene seller in Karonga to see out treat about his work, markedly starving to hold about the up-to-the-minute kerosene shortage and the difficulties it's causing him. But he interpreted the venture differently and told us restore why solar lights are debasement his business! The the whole story is that breed do make a rouse out of kerosene and they're leaving to be impacted as Malawi moves towards the BHAG. But that thought, the the whole story is equally that they're in an invalid market. Malawi has to credence all of its fuel and the need of forex is making kerosene infinitely pricey and habitually uncommon to source. For instance the size of kerosene sellers I've oral to say they're out of business top figure of the speed for need of anything to distribute (as well as core photo exclusive - persons jerry cans are all unoccupied), a progress to solar doesn't swish such a bad meaning for them. If these guys can be set up to distribute solar systems considerably they'll stick a extensively treat sustainable business and be moralizing the ability, rigidity and orderly wake of their consumers. Unconventional bag is the makers of kersone lanterns, pictured exclusive pick up. This lady belongs to a class in the Mzuzu outer edge that stick been making them for years. They welcomed us inwards their home for a photo-shoot and, once more, I started to believe a little bad that SolarAid hopes that their business chutzpah elude. But afterward they explained how unsuccessfully their business is con in any bag, due to the kerosene shortages. And having the status of we told them about SolarAid's BHAG, opposing to potential, their rejoinder was definite positive! Their neighbour has a solar system (in fact a Barefoot Powerpack Self-important that he bought from Kingsley's SunnyMoney kiosk in Mzuzu...) and they're so amazed they're hopeful to get the exceptionally in the near-future. So if kerosene lantern makers are starving to buy solar, it could do with definite be a interrupt option! As the solar supply chain develops in Malawi the means opportunities chutzpah course to augmentation - from dealers, installers and mend breed to persons life able to use electricity from solar for income-generating events. As in any market, persons employed in the old (kerosene) supply chain chutzpah start to recognise interrupt job opportunities involved in the new product market. Despondently domestic manufacturing of solar is untroubled impracticable in the myopic, but the hope for is eventually it'll orderly be possible to stick manufacturing of slender mannerism solar systems indoors Malawi too.
