5 de marzo: Dia mundial de la eficiencia energética

dia_eficiencia_energetica
Hoy, 5 de marzo, se conmemora el Día Mundial de la Eficiencia Energética, una fecha con la que se pretende concienciar a la población en el uso racional y eficaz de la energía, apostando por las fuentes renovables. El concepto se puso de relieve en 1998, con motivo de la “Primera Conferencia Internacional de Eficiencia Energética”, desarrollada en Austria como una medida de acción frente a la posibilidad de agotamiento de los combustibles fósiles a corto plazo.
En esta cita participaron expertos y líderes de diferentes países, que discutieron y abordaron las posibles soluciones de cara a una futura crisis energética, debatiendo sobre las políticas que podrían aplicarse para contrarrestar el cambio climático...

Researchers Discover Solar Wind Energy Source That Could Revolutionize Nuclear Power

Using data from a NASA aircraft, scientists have identified signs of an energy source in the solar wind that has caught the attention of fusion researchers and that could revolutionize nuclear power.

The discovery intends to solve a decades-old mystery: What heats and accelerates solar wind?

http://science.nasa.gov/media/medialibrary/2013/03/08/splash_big.jpgAccording to researchers from NASA “The sun is literally boiling itself away” trying to liken this phenomenon to the steam from a pot of water boiling.  However, solar wind does something that steam in a kitchen never does. As steam rises from a pot, it slows and cool. As solar wind leaves the sun, it accelerates  and something inside solar winds continue to add heat even as it blows into the cold of space.

Since decades, finding this “something” has been the goal of researchers and the answer has ...

Smart, Rich People Buy Electric Vehicles

Recent studies have suggested that Electric Vehicle (EV) owners are typically highly-educated and wealthy. So if you want to become highly educated and well off, buy an EV… maybe. Sadly, I don’t think the chicken-and-the-egg conundrum applies here. These studies also emphasized that the reason people buy electric cars is typically for the cost savings, not the environmental benefits.

At this point, due to the high price tag, EVs are typically purchased by individuals with a lot of money. The two highest selling electric vehicles in the US, the Nissan Leaf and the Chevy Volt, retail for about $36,000 and $40,000 respectively before the $7,500 government-provided tax-credit. The growth of EV sales has been slow, representing only about ...

Google Continues Investment in Renewable Energy

Tech giant Google is continuing to grow its renewable energy investment portfolio.  On Thursday, Google announced a $75 million equity investment in an Iowa wind farm, bringing Google’s total company-wide renewable energy investment to $990 million.

After shutting down its renewable energy R&D operations last year, Google has since been pouring investment dollars into renewable energy project financing and it still looks to purchase renewable energy and generating installations for their vast energy needs. Google has also agreed to long term Power Purchasing Agreements from NextEra and other companies who operate wind and solar facilities...

What Obama’s Reelection Could Mean for Combating Climate Change in the US

After what some considered an underwhelming first term for President Obama when it came to renewable energy integration, organizations in that sector are striking an optimistic tone after the president’s reelection. It is clear that Obama’s second term will be more beneficial for renewables than if Romney were to have been elected, but the Republican controlled House of Representatives could make it difficult for Obama to pass some anti-climate change initiatives.

Obama hopes to empower renewable energy sources.

Here are a few of the initiatives that have a much higher probability of happening now that Obama has been reelected:

Google Crisis Map for Hurricane Sandy

Google has developed a map which provides separate layers for the most important information, ranging from the storm’s current position and three-day forecast to a river flood outlook, storm surge probabilities, public alerts, and the locations of evacuation routes and emergency shelters.They have an additional more detalied map for New York City displaying such info as evacuation zones, evacuation centers, Red Cross emergency shelters, and even links to webcams displaying...

Artificial Clouds to Quell Global Warming

It’s not a new idea, neither science fiction. The process, known as “Marine Cloud Brightening“consists in artificially producing clouds over the ocean in order to cool the Earth.

How?

Futuristic ships would trigger salt water to the sky, creating a shield of clouds. The clouds would hopefully be thick, bright and large enough to reflect the sunlight back into the space, cooling the surface of the ocean.

Marine cloud brightening

David Young stated that this process “could achieve as much for the planet carbon cuts would, but at a fraction of the cost. It’s important to note that this technology wouldn’t reduce carbon emissions or tackle the causes of global warming, but would mask its effects”.

Projects like this are always controversial...
