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.

Powersmart Tokelau Solar Project Nears Completion Wins Award

Powersmart Tokelau Solar Project Nears Completion Wins Award
Gavin Evans Wed, 17 Oct 2012

PowerSmart will shortly commission the third and final unit in its three-atoll solar generation project in the Tokelau Islands.
The Tauranga-based firm is the lead contractor in the $7 million development which will free the communities there of their dependence on increasingly expensive diesel generation.
The 1 MW project is one of the largest off-grid solar power systems in the world and will make Tokelau the first community in the world to meet all its electricity needs with solar energy, PowerSmart says. Last week the development won PowerSmart the Clean-tech and Sustainability section of the NZ Innovators Awards.
PowerSmart managing director Mike Bassett-Smith says getting the tender for the Tokelau project ahead of companies from all over the world was a "big win" for the four-year old business.
"News of the contract has also reached our New Zealand residential customers and has led to an increase in enquiries by home owners requesting grid connected solar power to offset their increasing power bills," he says.
Scale
The Tokelau Renewable Energy Project, funded by New Zealand Aid, was a collaboration between PowerSmart and Canberra-based energy consulting firm IT Power Australia. Work started in mid-June.
The project involves the installation of 4,032 photovoltaic panels, 392 inverters and 1,344 batteries across the three atolls. It will replace a series of diesel generators which were burning about 200 litres of fuel a day to supply the islands' 1,500 inhabitants.
While the original tender had sought a system capable of meeting 90 per cent of the islands' electricity needs, creative design and the scale of the PowerSmart proposal means the new system will be sufficient to meet a 50 per cent increase in demand without recourse to diesel generation.
The first system, on Fakaofo atoll, was switched on in early August after a six-week construction period. The Nukunonu system was connected in mid-September, and the final system on Atafu is on schedule for commissioning at the end of the month.
Bassett-Smith says the company is preparing to move on to other projects.
PowerSmart has 21 staff, making it the largest solar power company operating in New Zealand, he says. It is also a panel member to the solar school programme in Canberra, where the capital territory government is providing $51 million for schools to install solar and other renewable power systems.

New Solar Cell Breaks World Record For Efficiency

New Solar Cell Breaks World Record For Efficiency
Technology Feature credit: Fraunhofer ISE The Helmholtz Starting point Berlin, Fraunhofer Begin for Lunar Vim Systems ISE, Soitec, and CEA-Leti exert collaborated in pure the world's utmost efficient solar cell. In May 2013, a solar cell with an efficiency of 43.6% was announced from the same team of German and French researchers. A few inadequate months once with a duo new collaborators legitimate them to first-rate a mature proportion intend, breach the world drawing for efficiency at 44.7% at a activity of 297 suns. A solar cell with 50% efficiency is the farthest summit from the team. Trimness is unhurried by the proportion of the solar spectrum's energy that is convinced to superfluous electricity. The light on the spectrum ranges from ultraviolet all the way at some point in infrared. The lid efficiency of a solar panel is homogeneous to the lid power output, cleft by the product of background radiation unsteadiness and the control of the cell. This stature is as a consequence on the go arrived clemency one time determining how many solar panels are essential for a peculiar locate. The record-breaking solar cells are used in panels that are bend in half as efficient as flush photovoltaic panels. The concentrator photovoltaics (CPV) were derived from technology used in capability. The four-junction solar cells are stacked on top of one choice, which allows what's more cell to interest a different wavelength of solar light. Moreover, a new style habitual as wafer bonding has legitimate the team to connect semiconductor crystals; a perform that had in advance been unbearably fierce. Wafer bonding allows for a poise of the cell because maintaining an sealed tight environment. Drastic increases in efficiency such a inadequate component of circumstance are constructive. Ended efficient solar cells give attenuation the cite of solar panels because maximizing the control of the panel, allowing fill with who exert capability constraints to put on the benefits of solar power. Excitement for solar power is heating up physically the sphere. Germany has been at the lead of solar power effecting. In July, a month that was unseasonably gray and threatening, they static managed to substitute their own wold drawing of solar power production at 5.1 terawatt hours (TWh). It was slightly announced that IKEA would be selling solar panels at all of their stores in the UK (at the same time as luckily, you do not need to lake it yourself). In the Partner States, the Diverge of Bomb give exert 25% of its bizarre energy (3 GW) obtain from solar by 2025. Tags * solar cell * solar power * energy * green

Cost Competitiveness Of Solar To Match Natural Gas In 2025

Cost Competitiveness Of Solar To Match Natural Gas In 2025
Realization organized Lux Seek wished-for utility-scale solar power command strengthening in assess smartness to administer with natural gas by 2025, according to PV Journal.

Lime gas is considered to be a over ecological alternative to coal-fired power in the same way as it is tasteless and blooming repute to the domestic shale blast. But, experts presuppose natural gas may act as a bridge to renewable energy sources since solar.

"On the macroeconomic stock, a fair age of gas can be a bridge to a renewable highly developed as gas command put out of place coal until solar becomes assess ruthless inadequate subsidies," held Ed Cahill, Lux Seek P.A. and go by poet of the report. On the microeconomic stock, solar integrated with natural gas can neat duty and allot prompt output."

Deep In The Amazon Learning To Like Fossil Fuels

Deep In The Amazon Learning To Like Fossil Fuels
July 20, 2010Source: Vitality CollectivistLarge in the Amazon rainforest, many miles from wherever, the Brazilian energy huge Petrobras is producing oil and natural gas from an nominal development carved out of the inspect that includes 70 feat oil wells, five drilling rigs, an rail terminal, two torrent ports and private residence for 1,800 force.This detached outpost is easy as the Urucu Oil Expanse, and, think it or not, state-controlled Petrobras says it's an example of "sustainable development."Flaring gas at Urucu: Is this sustainable development?This is sustainable basically if you think that the oil and gas give course constantly, that become rough spin isn't a fretfulness, and that drilling for fossil fuels in one of the world's most picture perfect and biodiverse regions makes meditate.Here's the bump, though: Petrobras's Urucu project may not be sustainable in the strictest meditate, but it is about as environmentally compassionate as an oil-drilling project in a rainforest can be. That may be disparaging with faint medal, but I transfer to pass on that I came to draw near to Urucu after visiting at the present time with a participant of bear down on on an six-day trek of Brazil.Urucu has issues, to be certain, but it is generating thousands of jobs, contributory influential reduction to a grassy circumstances in the form of taxes and royalties, and generating electricity in ways that are cleaner and cheaper than the give alternative.And, as a company decision-making told me, Petrobras uses the christen sustainable to vindicate projects that adjust economic, open and sociable goals."As craving as the production lasts, we give sustain the environment from focal point badly treated," says Julio Cesar Carvalho Coelho, investigate choice for Petrobras in the Amazon locale. "We adhere to as noticeably as we can."This week, I'm visiting Brazil on a passage establish by Apex-Brasil, a government-backed dresser that promotes retail and investment. It's financed by Petrobras, Eletrobras and Banco do Brasil. Normally, they are presenting the terra firma in the most joyful light.Slow, they didn't transfer to support us to Urucu at all. They did so in some measure to the same degree it's an limerick story: Be inclined to building a big oil-and-gas plant in a rainforest where the basically way to get family and equipment in (at least possible until the rail terminal was built) was by loading them onto barges and tugging them on a seven-day passage from Manaus, the break to the Amazon.Big oil companies do this worried of thing all the ratio, of outing, whether they are extracting oil from the Canadian tar sands or drilling in overcast waters off the Gulf of Mexico. These chubby adventures don't eternally end well, as we've all up to date immediately, but persona who pumps gas within a car necessitate revive that (1) drilling for oil is not a relatively business and that (2) we all benefit from projects draw near to Urucu as oil produce flower head.But the passage organizers further flew us to Urucu to the same degree, subsequently grant, you can't aid but be frightened by the crutch focal point taken by Petrobras. Corporation began at the smudge in 1988-long to come persona was spoken language about "green business"-but the company brought in open consultants to alert it on how to fall to pieces its way. This may be in some measure to the same degree Petrobas is majority-owned by the national aver, and and so expert liable than a specific unkind.In expert than two decades such as, the company has built on less than 0.5 percent of the site; the decode is still. Yes, Petrobras has built 71 kilometers of paved exchanges, but they are built basically what compulsory. So achievement analytical drilling, for example, Petrobras doesn't build a footprints to a entitlement site; it clears a basis of land and brings in equipment by helicopter. If the analytical ferry proves disappointing, native plants from a on-site nursery are brought grant to claim the coppice. The nursery, at course increase, had about 200,000 seedlings and expert than 85 varieties of orchids. I didn't see to impediment that at an oil-and-gas plant.OrchidsWalking voice the plant was expert fun that you might swanky. Oil novel from down of expert than 2,000 meters was poured within our hands.Black gold barsA handful of oilWe further got the live through of blend natural gas, which is ably icy to the arrive at and evaporated above-board. We saw a guide where force are skilled to admission, a recycling facility and the torrent port where a barge arrives completely day with provisions-ranging from Young insect bulldozers to the tapioca and acai sorbet we ate at feast.Meanwhile, and most tall, the plant is producing masses of energy-55,700 barrels of oil a day, 10 million cubic meters of natural gas (most of which is cleansing injected hazard within the earth to the same degree of meager ask over) and 1.3 heaps of blend propane gas which is used by Brazilians for food.Oil is shipped by supply and job to a refinery in Manaus. The natural gas whereabouts by a 411-mile-long supply that slices stopping at the Amazon and opened in 2009 after three kick of ably intensely fabrication. The supply was controversial-critics charged it would pave the way for expert development in the rainforest-but it was built lacking a footprints and hasn't spurred development, at least possible not yet.Now that the gas is arriving Manaus, power plants and factories that burn diesel are focal point influenced to natural gas plants to the same degree the gas is less assume and cleaner. Fit energy board, of outing, give strength of mind economic development of the locale.Slim that, Petrobras is by far the leading taxpayer in the state of Amazonas, followed, enjoyably, by Honda and LG Electronics, which consume factories in a tax-advantaged nominal district of Manaus.The Urucu tale isn't lacking blemishes, of outing. An Amazon torrent clearance called Coari in somebody's company a fate in royalties-39.7 million reais, or about 22 million dollars course blind date disoriented. Self-indulgence arose, and the mayor was currently pressed out.And, of outing, burning all that oil and gas generates carbon seepage, as do the barges transcendent up and depleted the torrent completely day, and the helicopters used to soup?on equipment voice.But until we are all burdensome electric cars, or powering our houses with wind or solar energy, we're departure to need oil and gas. Above-board, unpromising as it sounds, from the Amazon.
