The transition to a fully-renewable global energetic system has to be done in small but sure steps. New inventions pave the way towards sustainable technologies, and their experimentation on small and medium scale improves their survival chances and lowers their implementation price.

If we could somehow invent a reliable technology that could “eat out” all the excess CO2 from the atmosphere in a large scale, we could turn back to where we started from a hundred years ago, reducing global warming and the change of climate.

The run after the new gold, the unlimited and cheap energy, is being pursued all over the world, not only in the US. There are states, like Israel, where solar power has been harnessed for decades in the form of hot water for its inhabitants. All those solar water heaters have been build by economical [...]

The Holy Grail of energy was, is, and will be the solar power. Numerous solutions of converting solar power have existed along the centuries, and people have always used the Sun to power things up, except for the last hundred years or so - that’s the main reason we all got into troubles with mother [...]

More and more research studies show the fact that biofuels, ethanol, and other zero-carbon burning fuels do more damage than they do good in the long run. According to a recent study, it looks like ethanol, the petrol companies’ saving field, consumes up to three times more water than it was previously thought, as MIT’s [...]

A space-based solar electricity program could soon power the Californians’ homes. The project belongs to the state’s biggest energy company, PG&E, and it aims to generate 200 megawatts in the next 15 years. The company hopes that its plans will become operational until 2016 and is now trying to establish a partnership with a company [...]

The world’s largest solar plant is about to be built in Florida. The construction will begin in June next year, and the entire project will cost approximately two billion dollars. A Florida utility company and a real estate developer intend to establish the United States’ first town powered completely by solar energy

As I have said it many times before, inventions in the field of hydrogen storage are most desired, because hydrogen can be created easily from solar power, and offers nothing but water at the other end of the equation.

There have already been successful experiments involving solar powered boats, and there have already been people sailing them in the last ten years. Still, all of them have something in common: they use photovoltaic cells as an intermediate between the sunlight the mechanical work.

Burning things to get energy is not something new, in fact this is what we’re trying to get rid of. I usually don’t promote “habits” like this on this green blog, but, nevertheless, there are a few cases where this can be considered alternative energy. Or, at least, you could say it’s an alternative to [...]

Geothermal energy is considered to be the ultimate energy source in terms of reliability. Since it doesn’t depend on day or night, or other external factor, it is practically undisturbable and has a huge potential. The US already has the world’s greatest geothermal energy usage, but the production points are limited to a few areas [...]

Most of us still use today the traditional incandescent light bulbs to light our homes. But as the traditional light bulbs have a high energy consumption, most turn nowadays to compact fluorescent light bulbs (CFLs).

Seeing that regular wind turbines produce electricity at a rate of about 20 to 25%, Magenn Power thought of an air-floating wind turbine that would revolutionize the way these energy machines are made.

While there’s no Hancock to save the world from global warming, I guess we have to do that ourselves. We try and try, struggle

The use of wind power has been around for centuries, from the simple sail to the sophisticated windmills. The inconvenience of harvesting wind energy is that most of wind-farm sites are placed far away from the areas that need the power.
