Google says it wants to power 100% of its operations from renewable energy.

Google has announced a slew of renewable energy projects, as it moves to meet its commitment to power 100 percent of its business from green energy sources.

In what it calls the “largest, and most diverse, purchase of renewable energy ever made by a non-utility company,” Google said it has added 842 megawatts (MW) of renewable energy to its data centers, which nearly doubles the amount of clean energy it has already bought. Most of the renewable energy has been purchased for locations in the U.S., but Google said it has added more than 150 megawatts from a solar plant in Chile and a wind farm in Sweden.

An emerging class of atomically thin materials known as monolayer semiconductors has generated a great deal of buzz in the world of materials science. Monolayers hold promise in the development of transparent LED displays, ultra-high efficiency solar cells, photo detectors and nanoscale transistors. Their downside? The films are notoriously riddled with defects, killing their performance.

For an Israeli start-up, one answer to global warming is blowing in the wind. The company called NewCO2Fuels, or NCF, has been developing its own version of a technology that allows heat-trapping carbon dioxide emissions to be captured and recycled back into useable fuel.

It sounds complicated—and it is—but the company’s founders say it holds real potential in the fight against global warming.

Such capture technologies have gained increased attention as countries seek alternative methods of cutting back on greenhouse gas emissions, the main culprit in global warming.

A common criticism of a total transition to wind, water and solar power is that the US electrical grid can’t affordably store enough standby electricity to keep the system stable. Now a researcher proposes an underground solution to that problem.

A solar cell is basically a semiconductor, which converts sunlight into electricity, sandwiched between metal contacts that carry the electrical current.

But this widely used design has a flaw: The shiny metal on top of the cell actually reflects sunlight away from the semiconductor where electricity is produced, reducing the cell’s efficiency.

Now, Stanford University scientists have discovered how to hide the reflective upper contact and funnel light directly to the semiconductor below. Their findings, published in the journal ACS Nano, could lead to a new paradigm in the design and fabrication of solar cells.

To suggest that quantum mechanics and gravity are on the verge of being reconciled would be, to the physics world at least, as significant as the discover of splitting the atom. While splitting the atom might have led to the nuclear bomb, it also led to the technology of nuclear power, i.e. nuclear fission, which, if harnessed properly, creates a renewable and sustainable energy resource. The problem has always been that quantum mechanics — the rules that govern sub-atomic particles — and gravity, the rule that governs mass as we know it (the stuff we can touch and feel), do not agree with each other. The question has always been, what is it that “unifies” these two theories? Is quantum mechanics God playing dice, as Einstein suggested?

“God doesn’t play dice with the universe.”

By 2030 solar energy will have the capacity to meet all of our energy needs. The production of food and clean water will also be revolutionized.

If we could capture one part in ten thousand of the sunlight that falls on the Earth we could meet 100% of our energy needs, using this renewable and environmentally friendly source.

As we apply new molecular scale technologies to solar panels, the cost per watt is coming down rapidly. Already Deutsche Bank, in a recent report, wrote “The cost of unsubsidized solar power is about the same as the cost of electricity from the grid in India and Italy. By 2014 even more countries will achieve solar ‘grid parity.’”

While solar or wind farms are now contributing more energy than ever to the world’s power supply, traditional energy sources are often required at peak times or to supplement renewable sources during dips in availability — at night, for example. So Canadian startup Hydrostor has invented a system of pressurised underwater balloons that can store renewable energy until it’s needed, which could reduce the need for diesel or gas as a back-up source of power.

The company says its solution can last twice as long as the best batteries we have today, and at a much lower cost. The first facility has been set up in Lake Ontario near Toronto, with a series of balloons set 55 metres under the surface of the water and connected to the power grid via a pipeline.

“Compressed air’s been around for 40 years,” Hydrostor CEO Curtis VanWalleghem told Canadian Manufacturing. “It’s finding places to store the air that’s been the problem [and] why it hasn’t been massively adopted. We open it up to thousands more sites because we use hydrostatic water pressure.”

Tech behemoth Apple is set to become the first completely solar-powered company in Singapore.

As part of a long-term partnership with Sunseap Group, Apple will draw upon Sunseap’s vast network of more than 800 solar panel-equipped buildings, which will satisfy the energy requirements for the company’s forthcoming 2,500-person corporate campus and retail store operations in Singapore.

According to Lisa Jackson, Apple’s vice president of Environment, Policy and Social Initiatives, the company aims to completely kick its dependence on fossil fuels and rely instead on renewable energy sources for its facilities worldwide.
