For algae to power our cars and planes, production needs to be low carbon and cost effective, which means working with natural processes, not against them, say scientists.

Algae could become an important source of sustainable biofuel, as production doesn't compete with food crops for land. But we may need to change the way we grow algae from closed systems to open ponds if it is to be low-carbon and cost-effective.

Microsoft has committed to become carbon neutral beginning on July 1, the start of the company's new fiscal year. The shift results from three years of internal discussions within the company to improve Microsoft's carbon footprint and environmental performance. The company will roll out the new changes, including a new accounting system, across its operations in over 100 countries.

Backcountry pro snowboarder Jeremy Jones says he’s seen the effects of climate change up close after 18 years of heading to Alaska for deep winter powder.

“Our season ends a week earlier than it used to. The glacier we use to land on, we can’t anymore,” Jones said.

t’s a big part of why Jones formed Protect Our Winters in 2007 to unite snowboarders and skiers to save what they love.

Scientists at USC have developed a potential pathway to cheap, stable solar cells made from nanocrystals so small they can exist as a liquid ink and be painted or printed onto clear surfaces.

The UK and US will work together to develop "floating" wind turbines to harness more offshore wind power at a potentially lower cost, the government said on Monday.

Before this week's clean-energy meeting of ministers from 23 countries in London, the government announced it will collaborate with the US in developing wind technology to generate power in deep waters that are currently off-limits to conventional turbines.

Goodwill Ambassadors Unveil WED Challenge and Chance to Win Fuel-Efficient Cars.

World Environment Day (WED) 2012 is aiming higher than ever before.

Greenpeace reiterated its call for an end to deforestation in Brazil by 2015 and globally by 2020 during its launch of an awareness-raising expedition down the Amazon River aboard the Rainbow Warrior.

The Danish government has stepped up its green energy and carbon reduction targets for 2020, hailing the plan as the "broadest, greenest, and most long-term energy agreement" it has ever reached.

Danish minister for climate, energy and building, Martin Lidegaard, confirmed on Friday that parliament had agreed a new set of goals designed to wean the country off oil and gas.

The future would appear bright for the electric car. Gasoline prices are high. The government is spending billions on battery technology. Auto companies are preparing to roll out a dozen new electrified models. Concern is growing about the climate impacts of burning oil. And tough new fuel economy standards are looming.

This year’s Earth Hour, an event where people and businesses worldwide turn off lights to raise awareness about climate change, will extend to outer space for the first time.

World Wide Fund for Nature (WWF), the event’s organizer, said the one-hour switch-off will reach the International Space Station (ISS), a habitable artificial satellite in the low earth orbit.
