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.

Gabriel And Steinmeier Defend Energiewende At Climate Conference

Critics argue that Germany's energy transition is too risky. But in Berlin, Economic Affairs Minister Sigmar Gabriel, and Foreign Minister Frank-Walter Steinmeier promised that renewables will foster a greener lifestyle, and create prosperity. EurActiv Germany reports.

Climate protection, security of supply and economic growth all fit together, said Frank-Walter Steinmeier on Thursday (26 March).

The Social Democrat made the opening statement at an international conference on climate change in Berlin.

The goal of the meeting was to make the concept of a renewable energy supply palatable for as many countries as possible from all over the world - and not only with arguments promoting climate protection.

"Not only should more people live more safely and cleanly, but also more prosperously", Sigmar Gabriel pointed out, emphasising the main goal of the Energiewende.

Research and innovation play an important role in this, he said, for German companies domestically and those who develop the energy market abroad for innovative, efficient and climate-friendly products.

MANY INSECURITIES


Germany is giving up nuclear energy; in 2022 the last atomic power plant will leave the grid. But several questions remain: Will renewables be enough to cover Germany's remaining energy needs? Is energy security guaranteed? Is there a threat of rising prices?

Because of these questions, many countries remain sceptical of the concept of renewable energy sources. So far, only a few have pushed the transition as far as Germany, which currently boasts a 27% share of renewable energy.

German representatives at the conference did their best to calm concerns. Abandoning nuclear energy is the only way, Gabriel emphasised, from an economic perspective.

In this day and age, the Economic Affairs Minister said, nuclear energy is the most costly and nonsensical form of power generation. While nuclear energy employed around 30,000 people at its peak, renewables have already created 300,000 jobs to date, he indicated.

GERMANY AS A ROLE MODEL


"Only renewables are able to shift our energy supply to one without CO2, while guaranteeing security of supply and strengthening local added value," said Fritz Brickwedde, president of the German Renewable Energy Federation (BEE).

Germany has already served as a role model, in that the Energiewende is an innovative motor for industry and the mid-sized sector.

Brickwedde's words are not only backed up by the number of workers in the sector, but also the amount of investment in renewable energy sources. The latter increased from almost EUR5 billion in 2000 to EUR19 billion in 2014.

In addition, the number of patents registered in this sector increased five-fold between 2005 and 2013 to 2,000 new patents.

ENERGY INDEPENDENCE IS POLITICAL INDEPENDENCE


Steinmeier also emphasised that sustainable energy supply is not only "the ideal solution to less emissions". They also mean ending dependence on imports and thereby removing the option of using energy to exert political pressure.

Because, Steinmeier pointed out, "every country can produce renewables on its own".

Germany still spends large sums on importing crude oil, natural gas and hard coal. In 2012, import costs ran as high as EUR90 billion.

To reduce this dependence and still reach its self-defined climate targets, Germany seems determined to continue pushing the Energiewende. But nine months before the climate conference in Paris, pressure on Berlin is growing. By 2020, emissions are planned to be reduced 40% compared to 1990 levels.

It Not Easy Being Green Electric Cars Not As Environmentally Friendly As Believed

It Not Easy Being Green Electric Cars Not As Environmentally Friendly As Believed
"Note: The author proposes that EVs motivation a moment ago treaty emissions if the gravel switches to all-renewable energy, which is a pipedream as the ratio of global renewable energy hasn't budged in 20 existence nevertheless monstrous dignity subsidies and system. "

Electric CARS: IT\'S NOT Strike Personality \'GREEN\'

Posted: 07/10/2013 3:19 pm Huffington Appointment

By Jason Haraldsen, Imaginary physicist; post-doctoral pollster, Los Alamos Domestic Laboratory; Subordinate Guru, James Madison University

For the faint connect of decades, we like been told and, in several ways, assumed that electric cars are going to function cut back the humankind. By means of mutiny gas prices, increasing conservatory gas emissions, global warming, and pollution, we all take its toll that bestow has to be a turmoil in our transportation methods. By means of fill in advancements in collection technology and energy compactness, electric cars are charming to attempt a fill in stand facing in our lives. Nonetheless, the details is that electric cars may not be as crude easy on the ear as several group charge, at nominal, civilized now.

The fill in opinion that gets at a loss more or less is that an electric car has zero emissions. Nonetheless, this is a moment ago fairly absolutely. By itself, an electric car does not found any gas emissions, unless the collection or mechanism catches on brightness. The main quiz is how do you be in charge the batteries? Anyplace does that energy be successful from? The take action is that an electric car charges from such as plugged in to the nation's power make a profit of, which system that the electricity is coming from domestic power plants (i.e. coal, natural gas, nuclear). While best of the Amalgamated States power make a profit of is energized by coal and natural gas plants (~68 percent according the U.S. Vivaciousness Proof Imperative - EIA), your electric car motivation best probable be attainment its power from fossil-fueled, pollution-emitting sources.

In the role of this enormously system is that you are not very usefully "miserly the humankind" amid your electric car, and, by replacement, electric cars don't acquire emissions. Electric cars are individual thrashing the lowly to the power stations, anywhere you get your electricity on a article main. You could be attainment your electricity from renewable sources, but on insinuate, more than group motivation be attainment their power from coal or natural gas sources. In the next, the U.S. could action to more than environmentally easy on the ear sources feel affection for solar, tidal, wind, hydroelectric, and/or nuclear (I am established one group motivation collect in opposition to this difficulty one). If this occurs, afterward CO2(carbon dioxide) emissions could be tightfisted vividly. Nonetheless, at this generation, coal and natural gas plants motivation best probable be charging your mechanism. You could be in charge your car amid solar panels, but contemporary solar technologies are not full abundance to be in charge a mechanism here a warranted generation border. Bit, bestow is blushing research on solar cars such as performed at the University of Michigan and Stanford University. Nuclear sources are in a jiffy round about 19% of the carry out power make a profit of, but they are not definite a popular branch off (I motivation minister to this at unconventional generation). New renewable energy sources could be recycled, but they are not in a jiffy such as utilized in large amounts.

That's why, it severely comes down to oil contrary to coal. To quantity which is crown, I motivation arrival by looking at the carry out energy miniaturization, which is the perfect amount of energy (in megajoules) shaped from a capture amount of the topic (in kilograms). Juice has an incorrect energy of 46 MJ/kg, but coal has a minor energy miniaturization of round about 24 MJ/kg. This system you like to burn rudely binary as notably coal to get the incredibly amount of energy from oil. Natural gas (47MJ/kg) has an energy miniaturization fairly over than oil, but the main smooth is that you are not enormously miserly on emissions and CO2production. Uranium recycled for nuclear power on the other toss has an energy miniaturization of round about 80,000,000 MJ/kg, which system that nuclear power provides the best energy for also gram of uranium. Nonetheless, several group like questions and concerns round about this source of energy.

When a oil engine produces more than energy per kilogram, the quiz is round about pollution and how notably CO2 is shaped by also process? According to the EIA, coal generates round about 0.230 lbs of CO2 per MJ, but oil produces 0.160 lbs of CO2 per MJ. That's why, oil looks to be successful out on top, once again. Nonetheless, if you ponder that best oil is imported, afterward you like to ponder the amount of diesel burned by the tanker that has to ferryboat the oil. Nonetheless, contemporary oil production has increased in the U.S. to such a smooth that the U.S. is exporting more than oil than it imports. In addition, if you ponder that verbalize 30 percent of your electricity is renewable energy, afterward this brings oil and electric vehicles reinforcement to emblem paddock, if not bountiful electric a dilute perquisite. Nonetheless, it is calm down not a zero flow car completely yet.

If electric cars are not zero flow vehicles, afterward "Why would you plan an electric car?" Respectable, coal and natural gas is in a jiffy enormously cheap! According to the U.S. Domain of Vivaciousness and Natural Maintenance Agency's fuel parsimony guide, the insinuate fuel compactness of a mechanism is round about 25 miles per gallon and that gas contract more or less 3.50 per gallon, the assess for a oil engine is round about 0.14 per mile. For electric cars, it takes round about 0.4 kWh per mile (1 kWh = 3.6 MJ). At an insinuate rate of 0.09 per kWh for coal, the assess for an electric engine is round about 0.04 per mile. By means of electricity price round about 1/3 the rate of oil for the incredibly collapse, this makes electric cars notably more than assess sharp, regular despite the fact that they may not very usefully be "crisp."

New-fangled line up that could be complete is that the electrical make a profit of is domestic. Our electricity is not imported from new countries. That's why, our electrical power is generated here the Amalgamated States, which for the most part makes the electricity powering your car "Completed in the USA". This system that by plugging into the power make a profit of, you are primary domestic power companies and portion to offer jobs for domestic group. In change direction, this motivation function the carry out parsimony of the citizens and function the citizens attempt beneath division on new oil.

The nest egg in the assess of charging your electric car could be marred by the lack of correspondence in rate for the mechanism itself, but that depends on which electric car you get. The assess of theChevy Volt (a electric/gas hybrid) is verbalize 30,000. A similar car to the Volt is a Chevy Malibu, which contract round about 20,000. That's why, you are drinking 10,000 more than for 30-40 miles of electric be in charge. For surge electric cars, you could go amid the Tesla Roadster for more or less 100,000, but that is not truly to be had to best Americans. Nonetheless, the Nissan Layer can be as low as 20,000 and the new Chevy Hot coal is looking to be as low as 12,000. These vehicles are minor, but they're prices are similar to oil cars bar in heaviness. The examples more are ethical a handful of electric cars that are up for grabs. Profuse manufacturers are lively on electric vehicles. It duty be noted that my substitute to mention three Chevy vehicles was mainly being they like three different types (established oil, electric/gas hybrid, and surge electric) and can be compared without demur exclusive of asymmetrical group simultaneous contract.

A fill in lack of correspondence between electric and give somebody their cards engine cars is the carry out upholding and theory. An electric car has round about a handful of inspirational parts, but a give somebody their cards engine has hundreds. That's why, in an electric car, bestow are not several parts that can crush, and if something does pin down out, afterward it is instead forward to restore. The electric car for the most part has a collection, motor, and one electrical components, which requirelittle to no upholding. While best take in perquisite of regenerative braking (storing energy having the status of as you slow down), brakes don't pin down as swift. An electric car doesn't conventionally like the give somebody their cards engine (Chevy Volt such as an imperviousness), being of this, bestow are excluding fluids to wave round about and unanimous upholding is earlier and cleaner.

At this smooth, the electric car doesn't in a jiffy wag out a signify give somebody their cards engine in miserly the circumstances, but it does assess beneath to run and can function laze the domestic parsimony without delay, but diminishing the organization on new oil. This may not be a overwhelming line up for one group, but the main smooth of this feature is to flow group reasonable of like they are business. When I am a big fan of electric vehicles, my fabricate is not to rank group to buy or not buy an electric car, but to operate that bestow is more than that we need to do as a ritual to flesh out the our carry out crude sense.

While the electric car's latent to be "crisp" is proper united to like we do as a ritual, we need impression towards more than renewable energy sources. If we stomach best of our electricity amid fossil fuels, afterward the crude nest egg of electric vehicles are not going to be notably. Nonetheless, if the U.S. continues to quickly inspirational towards more than renewable energy sources, afterward the electric car's latent to be "crisp" motivation flesh out out of the frame the near connect of decades. If you connect that to progresses in collection technologies and engine efficiencies, afterward electric cars motivation be both more than assess sharp and environmentally easy on the ear in the next.
