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 Than Money Put People And The Planet Alongside Profits

More Than Money Put People And The Planet Alongside Profits
LONDON -- EVER SINCE I TOOK MY FIRST STEPS AS AN ENTREPRENEUR MORE THAN FOUR DECADES AGO, I HAVE BEEN MOTIVATED BY THE QUESTION OF WHAT BUSINESS CAN DO TO MAKE PEOPLE'S LIVES BETTER. COMING UP WITH AN ANSWER ISN'T ALWAYS EASY, AND FOR MOST ENTREPRENEURS, SUCCESS FOLLOWS A GOOD AMOUNT OF TRIAL, ERROR, AND FAILURE. ONE IMPORTANT SOURCE OF INSPIRATION IS TO LOOK AHEAD AT THIS WORLD A DECADE OR TWO FROM NOW. WHAT KIND OF FUTURE DO WE ENVISAGE AND WHAT KIND OF PRODUCTS AND SERVICES WOULD WE LIKE TO SEE? WHAT ARE THE ROADBLOCKS ALONG THE WAY? As it turns out, our planet faces a broad range of enormous challenges. How can we feed an ever-growing global population? What can be done to lift the world's poor, still well over a billion people, to a higher standard of living and a better life? How can we turn the tide on climate change? And will we ever manage to overcome our divisions and put an end to violent conflict, from Syria to the Congo? On a closer look, I feel that most of the big issues of our day are connected in some way or the other; and more often than not, they point to far greater systemic challenges. One of these is the way we have been treating our beautiful planet, destroying vulnerable ecosystems, wiping out biodiversity and depleting many of our ultimately limited natural assets. For instance, it doesn't require much wisdom to see the straight line that leads from a warming planet to desertification and soil erosion, to water stress and scarcity, and on to massive migration and abject poverty. Likewise, our insatiable appetite for fossil fuels has fueled unrest and armed conflict around the world. It's a vicious cycle, indeed. And it has been a major focus of my own advocacy over the last decades. But as much as I appreciate the seriousness of the situation, I don't dwell on gloom and doom. Challenges exist to be tackled head-on. I'd like to look at this web of interdependencies as a huge opportunity to drive progress and positive change -- through sensible policy, for sure, but especially through innovation and smart investments. As so often, entrepreneurs have a major role to play. The good news is that many are doing it already and at greater scale than ever before. It is one of the reasons why, last June, we launched the B Team, a global group of business leaders which aims to deliver a new way of doing business that prioritizes people and planet alongside profit -- a "Plan B" for businesses the world over. Zooming in a little, one of the big questions in the coming years is how we can ensure access to safe, clean and sustainable energy for our and future generations. Access to energy is a foundation of ensuring sustainable lives for 7 billion people, and despite the huge size and incumbent nature of the energy sector, there is lots of room for improvement. First and foremost, I see a huge amount of opportunity to use energy more efficiently than we currently are. This applies to more efficient cars and aircraft as much as it does to electronic devices. And it's of particular importance when it comes to buildings. As a recent report by the Carbon War Room pointed out, buildings are responsible for 40% of the total energy consumed globally, and one third of the world's carbon emissions. Not only is there a huge potential to reduce these emissions globally through greater energy efficiency (the equivalent of over 1.1 billion tons of CO2), but the financial savings of reduced energy use can be equally monumental: to the order of trillions of dollars globally. Second, new and disruptive energy technologies (from advanced renewable fuels, to electric cars that leave their petrol-powered rivals behind, to more efficient, lower-cost solar cells and intelligent ways of heating and cooling buildings) need adequate financial backing. Many investors are still reluctant to grapple with what they see as risky early-stage concepts. But I am convinced that some of these innovations and concepts will succeed, and organizations like the Carbon War Room are already helping to get billion-dollar markets off the ground that could save billions of tons of carbon emissions. The challenge is for investors to create scenarios where they can back these sorts of efforts without throwing too much money down the drain. The MIT Technology Review recently pointed out that, in the US, private foundations can count investments in start-ups as charitable grants - even if they go on to deliver massive returns. The catch is that the start-ups have to clearly be too risky for normal investors, and have to clearly serve a philanthropic role. But ways need to be found to ensure that resources go into the right ideas from the right places. This also means that the world needs to start a conversation about energy subsidies. Sceptics frequently argue that low-carbon renewable energy costs more than conventional fossil energy. However, as the International Monetary Fund pointed out back in March 2013, global energy subsidies are estimated to total about 1.9 trillion worldwide, or about 2.5% of global GDP. If these energy tax subsidies around the world were eliminated, global CO2 emissions could be reduced by over 4 billion tons (or 13%). For comparison, the whole world invested 244 billion into renewable energy in 2012; it would have likely been more, were it not for the unstable and uncertain subsidies and policies for renewables. To be sure, each of these challenges for the energy sector still represents a huge mountain to climb. But the relentless optimist in me likes to think that the "clean revolution" is not a choice between saving our planet and growing our businesses. Both are two sides of the same coin. With the right mix of innovation, investment and sensible regulation, I see success well within reach. More

7 Inspiring Stories Of Communities Taking Action For Climate

7 Inspiring Stories Of Communities Taking Action For Climate
Stories of communities taking strategy for the coarsen and refusing to hand out the plans of polluting fossil fuel companies are undergo spread and spread. Offering are directly a few inspiring coarsen acts of determination hard-working by doctors, villagers, students, farmers, and 92-year old veterans - kin directly require you.

1. CANOES VS. COAL

The Pursuit of the Conciliatory debris to agree themselves to downpour, they are battle exhort v coarsen change! Populace of the Conciliatory islands, along with the countries utmost helpless to rising sea levels, are taking the conflict to mass their homes aim to the fossil fuel industry. By the use of purist canoes, 30 Conciliatory Survive Warriors from 12 Conciliatory islands paddled hip the oncoming imprints of coal ships in an relocation to end down the world's major coal port for a day.

2. MAULES Cove Arrangement - "WE CANNOT Come to THIS TO Stem"

Australian mining mammoth, Whitehaven Coal, is set to build a remarkable open-cast coal search to dig up one of the major in the territory. The mine's CO2 output may well break on up to 30 million tonnes per meeting - like mad as good as to New Zealand's all-inclusive energy sector. The heavy party joined with anti-coal activists, through serious leaders, doctors and a 92-year-old digger, earnest they mood not agree this coal to be mined and burned. They launched a fiery gripe v the developments, swear tutor, non-violent strategy to illness v the mines. Not considering the protests the mining has begun, but the conflict is not empty.

3. THE Diary OF DHARNAI

The Dharnai defrayal in Bihar, India, has unconscious their congregation, and the nap of the world, how kin can starting point up to the climate-wrecking fossil fuel industry. This small defrayal from one of India's poorest states is lit-up by a solar-powered micro-grid. By bypassing the murky energy technologies of the before century, and by powering their party with sustainable solar power, the defrayal proved that kin can own and control their own clean and renewable energy.

4. A Midstream LOBSTER Boat CAN Imprint A BIG Swap

In May 2013, Ken Quarter and Jay O'Hara used their dumpy lobster yacht to barricade a shipment of 40,000 tonnes of coal spring for the Brayton Point Authority Station, the major coal plant in New England, US. They were charged with scheme, traumatic the compact and motor slyness violations and faced up to a choice of years in put behind bars. In a principal - and strange - winner for the coarsen disagreement, prosecutors in the US state of Massachusetts dropped charges v the two activists. Why?Let's let the Archdiocese Trial lawyer explain:

Wow. Let's consider all restrained activists taking strategy for our imminent are treated with the identical brassy indicate.

5. FOSSIL-FREE SCHOOLS AND CITIES

Dozens of universities and cities are committing to divesting in fossil fuels. Many of these commitments utilize as a estimate of students and people organizing and idiom to officials about the value of divesting from fossil fuels. See Pompous about everyone who's going fossil free!

6. Pursuit OF MAHAN

The tale of Mahan in India is the tale of a party battle to mass an obsolete tree-plant from a long-corrupt coal industry. The crusade of the kin of Mahan involved intercontinental backup and managed to, not truthful mass the tree-plant from for example rotary hip an open-pit coal search, but both achieved winner for the environment and the coarsen by spelling out the end of depriving coal in India. Coal fired up power plants are the major source of fake CO2 emissions. India now has an majestic way to scale up its intention on renewable energy!

7. At all Hang Opposed to COAL

Thousands of kin amalgamated hands to form an eight-kilometer At all Hang across the fringes of Germany and Poland to illness v lignite coal mining in the distance. 30 different nationalitiestraveled from cities all empty Europe to be give to. It was an exceptional paint the town red that brought joined Greenpeace volunteers, naive blue-collar organisations and thousands of members of the heavy party.
