The ocean occupies 70% of the earth’s surface and the waves that occur in them have the highest energy density. That means in a relative small area substantial energy can be generated making it the most viable and virtually inexhaustible energy source.

One wave-energy-harnessing device was developed by ORECon. They refer to it as a Multi-Chambered Wave Energy Converter. Anchored offshore at a minimum water depth of 50m, ORECon says, “it will tune itself to the varying wave strengths or frequencies to maximize the energy transmitted from the rise and fall of the waves.”

I didn’t quite understand that either until I saw the illustration below.

In February of this year, after 500 top scientist from 113 countries released a landmark report saying that they are 90% certain that global warming is caused by humans, some American scientists are recommending desperate-sounding solutions that sounds like science fiction.

They want to implement new technologies that are called geo-engineering. One idea is to put giant mirrors in outer space to deflect some of the sun’s rays from getting to earth. Cooling the planet as a result.

They are the next generation vehicles. The hybrid, plug-in hybrid, electric, or the hydrogen fuel cell vehicle - they all use alternative fuel. Fuel that carries a promise to take care of the planet. How? By burning less or no fossil fuel at all therefore reducing or eliminating emissions that heat-up the earth.

However inasmuch as a lot of people are clamoring for these green cars, there are also a lot of naysayers. They say, these vehicles whether hybrid, electric or hydrogen is not as green as the consumers are led to believe. Some are more bold into saying that they do more harm to the environment than cars run by conventional fuel combustion engines.

So let’s lay their cards on the table, those who are for it and those who are against it, and see how each fare. So everyone can appreciate the arguments, let me first give brief descriptions on how each vehicle operate.

It probably never crossed your mind how much power “the Internet” consumes every single day. Take Google for instance. It’s estimated that they are running over 450,000 servers just to process billions of search queries per day. To power all that, they spend US$24 Billion Million each year on electricity which is a whopping 240 megawatt annual electric consumption.

I did some search on Internet statistics and found out that there are about 10 million servers that are actually connected to the Internet. Now, that definitely would suck-in huge amount of power. Since fossil fuel is used to generate 70% to 80% of electricity worldwide, several tons of CO2 are dumped into the atmosphere just to run the Net.

Recently, I’ve encountered a bunch of Green Web Hosting Companies. They define themselves as web hosting companies that uses “green electricity,” electricity that is generated using renewable sources like wind turbines and solar panels.

A house that stays warm during winter and cool during summer (60 to 80 degrees F) without the use of electricity or fuel is what Enertia, a North Carolina-based sustainable homes designer/manufacturer has to offer.

The house uses free energy from the sun without fuel, combustion or pollution. The materials of the house which is mostly built of solid Southern Yellow Pine wood (which is renewed at a rate greater than what is harvested) absorbs and retains heat during the day and releases it during cold nights. On the other hand, by thermally connecting the house into the ground, the geothermal conditions in the earth cools it during summer.

But those are not the main keys to the innovation. As you can see in the illustration below, the house’s design incorporates a biosphere. According to Enertia, this gives the house its own “atmosphere” quite like of the earth that creates a comfortable living space despite the extreme cold or hot temperatures outside.
