"Our opponents say, again and again, that drilling will not solve all of America's energy problems - as if we all didn't know that already. But the fact that drilling won't solve every problem is no excuse to do nothing at all.

have a biking nemesis: During my regular rides around the six-mile outer loop of New York's Central Park, the big hill at the north (uptown) end of the park invariably sucks the very life out of my aging legs. Yesterday, however, pedaling up the big incline was another story altogether. It was as easy as climbing a small rise. My new-found prowess had nothing to do with any improved fitness, of course; it was the bike I was riding, the Twist Freedom DX from Taiwan's Giant Bicycle, Inc., which augments every pedal stroke with a finely timed electric boost.

A bipartisan group of 27 elder statesmen is sending an open letter to both presidential candidates and every member of Congress saying the country faces "a long-term energy crisis" that threatens the security and prosperity of future generations if swift action isn't taken.

Atlantic Canada's Bay of Fundy has some of the world's highest and most powerful tides. Every day, 100 billion tonnes of seawater surge in and out of the bay - a perfect source of clean, reusable alternative energy, if it can be properly harnessed. Tidal power isn't new, of course; small grain mills were powered by tides in Europe centuries ago. But tapping into the reliable, natural ebb-and-flow of water to generate electricity didn't begin until the 1960s.

Scientists at the Ohio State Institute for Materials Research recently announced that they have developed a new hyper-efficient solar material that is able to capture light from every spectrum of the rainbow. Whereas most photovoltaics are limited to collecting energy from a small range of frequencies, the new material is able to absorb energy from all spectrums of visible light at once. The breakthrough development heralds a new breed of extremely efficient solar panels on the horizon.

In a significant milestone in the deployment of flexible, printed photovoltaics, Konarka, a solar-cell startup based in Lowell, MA, has opened a commercial-scale factory, with the capacity to produce enough organic solar cells every year to generate one gigawatt of electricity, the equivalent of a large nuclear reactor. Organic solar cells could cut the cost of solar power by making use of inexpensive organic polymers rather than the expensive crystalline silicon used in most solar cells. What's more, the polymers can be processed using low-cost equipment such as ink-jet printers or coating equipment employed to make photographic film, which reduces both capital and manufacturing costs compared with conventional solar-cell manufacturing.

Are you looking for a career path that you have complete control over every part of the business? No more boss to worry about. Starting a greenhouse business may be something to consider.

If you don't already know it by now carbon dioxide is the leading cause of global warming. Since it is the largest factor in global warming it would be prudent for us to eliminate this emission first. Although we can never fully eliminate carbon dioxide, because we and every other air breating creature exhale it, it is possible to reduce it enough to the point it doesn't cause global warming.

More than 100,000 people attend; a testament to the popularity of sustainable building and renewable energy in the region. by Michael Fell Wels, Upper Austria [RenewableEnergyWorld.com] Last week saw the return of the World Sustainable Energy Days conference which is held every year in Wels, Upper Austria. Taking place over three days (plus a day of site visits), the conference has three main streams: the European Pellet Conference, the European Energy Efficiency Conference and Regional Biomass Action Plans. Austria is an apt location for the conference - along with Sweden it is well known as one of Europe's biggest users of pellet technology - and as the final remnants of this year's snow melted away it is plain to see why. With cold winters and real enthusiasm for efficient and sustainable building, the demand for renewable heat is strong. The country is also highly forested, providing ample raw material for pellet production in the form of sawdust and wood shavings from sawmills (along with other biomass waste).

As Sultan Al Jaber breezed into the room, wearing a flowing white dishdash and distractedly tapping on his iPhone, he looked every bit the harried chief executive. Any notion of a long chat was quickly extinguished.

Just in case you missed it, green careers are coming quick. Every time you turn around you get a new list of top green careers.

a self explanatory title......weird but true fact...........proves that every coin has two sides.

For every creature a home is an important factor. It provides protection from predators and affords shelter from the elements. Birds, in particular, devote considerable time to creating a suitable abode. The vast majority build their own nests, although there are some exceptions. For example, some owls use a hollow in a tree , and most falcons and nightjars dispense with a nest altogether and lay their eggs on bare earth.

Can you explain to me and the readers why solar panels are so expensive? Why can we not get the cost of this energy down to US $0.15 per kWh while we're paying off the equipment? Why are we paying for future production capability today? It is like the current electricity providers are saying, "Well, your house will use 12,000 kWh this year so we want our $1,800 now" or worse "give us 20 years up front" as the solar industry does today! If the solar market really wants to see a green planet then I feel they need to get the green out their eyes! Can they not see that they can truly make every home owner self sufficient if they bring their costs in line. It seems as though this renewable energy game is for the wealthy. If I want my home to be totally self-sustaining, it would cost me $80,000! A: Ian, I am happy to respond to your question since I have spent my own money on both my net-zero-energy home and my zero-energy office building - so I am acutely aware of the costs.

The world is already embracing various recycling methods, but it is not enough. Every household, including yours and mine, must participate even in our own simple ways.

Most people who work in this field would do engineering and mechanical tasks from the prior installation of wind turbines, its proper operation including the safety measures and precautionary alternatives that every consumer must follow, the maintenance and repair of such installations.

The UK's seas could provide enough extra wind energy to power the equivalent of 19m homes, according to an assessment by the government. The government's strategic environmental assessment (Sea) confirmed projections that an extra 25GW of electricity generation capacity could be accommodated in UK waters. This would be in addition to the 8GW of wind power already built or planned offshore, bringing the potential total electricity capacity of offshore wind to 33GW - enough to power every household in the UK.

Massachusetts is searching for every blustery nook and cranny it can find to boost wind energy production, from the tops of former dumps to a vast military reservation. Gov. Deval Patrick has set a state goal of generating 2,000 megawatts of wind power by the year 2020 - an effort that may require up to 3,000 wind turbines. So far, the state boasts a mere 11 commercial-scale turbines and dozens of smaller ones.

Car sharing has become an increasingly common concept today. What is it? Car sharing is the concept of sharing a vehicle rather than owning it outright. It is similar to carpooling, only you do not ride with other people in every case.

Using an exterminator that will practice the safest and most natural techniques for pest control can be reassuring and may be the only consideration for those who are determined to live green in every way.
