The Searaser takes a novel approach to wave energy generation. New owners Ecotricity - pioneers of wind power in Britain - are aiming for mass deployment in the next five years.

A hydropower turbine has the potential to not only create energy, but has also sparked the creation of both a renewable energy company and a renewable energy education program in Maine.

The agency is offering up open source modeling software to scientists, engineers and garage inventors too.

When you think about it, it's really Moon power!

The wave energy generators would help to both generate power and dissipate the power of the waves crashing against the shore.

Normally you can't have it both ways, unless you have a member of congress in your pocket.

A new microbial fuel cell can not only drastically reduce the amount of sludge from wastewater treatment plants, but can also produce clean energy at the same time.

Researchers have used abundant and inexpensive materials to create a tandem solar cell that can store solar energy as hydrogen for use at any time of day.

The groundbreaking technology has gotten even better with the ability to self-heal and produce hydrogen from dirty water.

A long-suspected secret behavior of water molecules in ice is seen for the first time using a new technique that could help develop energy alternatives.

This is one of those comparison posts that that could draw many angry comments: like Could Hype Sell An Inferior Hybrid? - Ford Fusion versus Toyota Camry did. Please carefully read the caveats.

It's ugly, but it sure can keep that car from cooking, and it is going to be seen from a long distance.

Clean energy is creating jobs and boosting local economies nationwide.

The rise of clean energy jobs is outpacing the loss of fossil fuel ones.

Yanaizu Town, Kawanuma District, Fukushima Prefecture is rural-at-best and about as far away as you can get from the big cities. The town recently made the news when Chiba

The heat in the upper six miles of the earth's crust contains 50,000 times as much energy as found in all the world's oil and gas reserves combined. Despite this abundance, only 10,700 megawatts of geothermal electricity

When huge volcanoes erupt, sending ash miles into the atmosphere and shutting down air travel for entire continents, the world can't help but take notice. Yet everyday, around the planet, smaller displays of geothermal force take place. Sometimes, it's f

When huge volcanoes erupt, sending ash miles into the atmosphere and shutting down air travel for entire continents, the world can't help but take notice.

Energy policy and energy use are not forces of nature beyond our control. It's all about choices; different choices set us off on different paths, but don't prevent us from switching course.

Plus... Shell announces first carbon capture project in the Alberta Tar Sands; Arctic oil and natural gas's high cost to limit their global share.

Geothermal power has a promising future, but so far it has lagged behind most of its other renewable energy cousins, especially wind and solar.

Do you think we need to shift to solar, wind, and geothermal energy? Then show some love this week in order to help grow this important societal transition.

Is it a geothermal system or a ground source heat pump? Yes.

In this case, the HORSE is a 'living' machine, not an animal, and has the potential to reinvent the food cycle.

It's time to put a stake through them and build efficient Passivhaus buildings.

Passive House multifamily buildings use almost no energy and don't cost much more than conventional buildings. They should be everywhere.

Much to the scepticism of our readers we’ve covered hot rocks at least once or twice before. In a nutshell, it’s a form geothermal energy derived from pumping water kilometres underground where it gets heated enough (by hot rocks!) to then rise back to

The next game-changing technology might not be in the form of an electric car with a longer range, or more efficient solar panels, but rather a better way to dry your clothes.

Air quality, choice of materials and finishes are also concerns in this house in Oregon.

Currently, New Hampshire is the only state in the northeastern United States that has not passed some form of renewable portfolio standards legislation. However, that may change soon. Last week, the New Hampshire House voted decisively in favor of a

Video profile of University of New Hampshire Ecoline™ project. Video credit:UNH and Waste Management.The beginning of a new decade reminds us to also look back at the past 10 years to see how everything from daily tasks to new technologies have evolved.

Beyond the headline, a really great overview of how globalization may well be entirely reshaped by energy constraints, for the betterment of local economies in places where manufacturing has been outsourced for years.

This rapper nails it, imho.

It learns your usage patterns but can do a lot more.

I knew that real-time data on our energy use would be interesting. But I wasn't sure how much it would actually save us.

A new study claims that energy efficiency is driving the Smart Home market, but in fact every bit of smart tech is a little vampire.

The current wind power installation has replaced millions of liters of diesel fuel and helped protect the islands' endangered animals.

Furthering a trend: As the United States continues virtually deadlocked on enacting any legislation pricing carbon or significantly promoting renewable energy, more Asian countries than China are likely to

10 coal plants in Chicago, Ohio, Pennsylvania, and New Jersey will be shut down sooner than expected.

Quoting directly from the Philadelphia Eagles presser: "The Eagles have contracted with Orlando FL-based SolarBlue, a

The latest figures from the EIA show renewable energy sources overtaking nuclear power in the US, through the first nine months of 2011.

According to the International Energy Agency (IEA), by 2018 renewable should overtake natural gas to become the world's second-largest source of energy (oil is #1).

UK households can now buy 15 percent green gas and 100 percent green electricity with one easy tariff.

A new wearable sensor technology that measures things like stance and force for sports also has the potential to harvest energy from waves, machinery or human movement.

Walking and other gentle movements could power the next generation of devices.

Could this be even more encouraging than a FitBit to get up and walk around?

The city council has begun installing solar-powered lights around the streets of downtown Nairobi.

From record investments in energy investments made by US states, to East Africa's largest wind power project, Chicago's smart gridization, to Chevron's huge fine being upheld, here's what we're reading today.

It's the first plant plant of its kind in the states that generates electricity from the temperature differences in the ocean.

There are huge gains to be made by boosting efficiency. Even if we can never get to 100% because of the laws of physics, we could get much closer than we are now.
