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.

Peru Aims To Cover Rural Electrical Gap With Solar Panels By 2020

Peru Aims To Cover Rural Electrical Gap With Solar Panels By 2020

(Reuters) - Peru plans to nearly close its gap in electrical coverage in rural regions by the end of the decade with a recently-awarded 28.5 million solar-energy contract, the government said on Wednesday. Ergon Peru S.A.C., which beat one other bidder on the contract awarded on Friday, will install 500,000 solar panels across Peru and guarantee their operation for 15 years, said Energy and Mines Minister Eleodoro Mayorga. Only 70 percent of rural Peru is now connected to the electrical grid, compared to 90 percent nationally. Mayorga said the photovoltaic panels will boost rural electrical coverage to 96 percent in five years - much faster than waiting for the grid to reach Peru's far-flung provinces. "This is a big leap forward," Mayorga said at a press conference. "Our goal is for all Peruvians to have electricity by 2019." Next year Ergon will install at least 65,000 of the panels, followed by 125,000 in 2016 and the rest by the end of 2018, Mayorga said. They will be installed on rural homes for the most part, but will also be used by schools and health clinics. Past government efforts to bring solar energy to poor provinces did not last as panels broke down, said Deputy Energy minister Edwin Quintanilla. "That is why maintenance is so important," said Quintanilla. "What is different here is we are guaranteeing the integral supply of electricity for 15 years through a private investment." Quintanilla said the company is responsible for fixing or replacing broken panels. Peru's mineral-rich rural regions are rife with disputes over environmental concerns and proceeds of mining projects. Peru is a top global producer of copper, silver and gold. Despite a decade-long economic boom in Peru, poverty rates still top 50 percent in some rural areas, where basic services are often lacking. (Reporting By Mitra Taj; Editing by Bernard Orr)
