Solar Funding in Germany Will Stop at 52 Gigawatts

Germany's energy policies have been very friendly towards the continual production of clean energy sources such as solar and wind power. While some of these policies tend to be structural and permanent, others are designed to be "temporary boosts" to help society rely less on fossil fuels and more on renewable energy sources. 

Peter Altmaier, Germany's federal minister of the environment, has announced that Germany will stop subsidizing solar energy by the year 2018 at the latest because the pre-set ceiling of 52 gigawatts of capacity should be reached by that time. 

          

AFP writes: "The system of subsidies, under which solar energy producers are paid a guaranteed price for each kilowatt-hour of power generated, created a boom in recent years, making Germany a global leader in the field. The farm sector in particular seized upon solar power as a chance to supplement income, and the low price of solar panels from Asia contributed to the craze."

Solar-Powered Computers for Off-Grid Schools

      In 2009, a 19-year-old graduating senior from Hong Kong's International School, Charles Watson, carrying a rudimentary computer, had took off a year from entering a university to travel to Nepal to work on a project he came up with while still in school: to provide off-the-grid schools with solar-linked computing power. "Once I got to Nepal, I was running a blog, taking photos and so on, saying 'We need computers,'" he says. "I did a fundraising run in Nepal and that raised enough to buy 30 computers at $300 each - $10,000 if you include the solar panels."
      Watson, an American who has be raised in Hong Kong, is currently 23 and still is not attending a university, despite being accepted at the University of Illinois, and doesn't plan on attending any time in the foreseeable future. Instead, he is the founder and chief of SolarLEAP, a nonprofit organization company whose computers are often assembled by his parents at their kitchen table, but they are delivering computing power to schools without reliable electricity, or none at all, in countries as diverse as Nepal, the Philippines, Ethiopia, and, he hopes, across the world.
       "As many as 1.3 billion people, a fifth of the world's population, remain without access to electricity," he says. Ten countries--four in developing Asia and six in sub-Saharan Africa--account for two-thirds of those without electricity. Unless further action is taken, it is projected that close to one billion people will be without electricity still in 2030.

Charles Watson and friends

        Watson has since branched out to Ghana, where he has installed 24 computers, each running on solar power in off-grid schools. After the projects in Nepal and Ghana were completed, demand in rural communities began to grow. Within weeks, organizations in India and Ethiopia were looking for unique low-power consumption computers to run in schools without electricity. Furthermore, Watson was looking for a way to continue the work without his direct, on-the-ground involvement, and thus SolarLEAP was born.
        Today, he has installed 200 of solar-powered computers in five countries with funding from non-governmental organizations and anybody he can solicit money from. "The transformation of schools is dramatic," he says. In 2010, after installation of his computers in Canumay School near Antipolo in the Philippines, the school moved from last place to a first ranking in its school district. He provided the first solar-powered computers to any school in India. "One in four people around the globe don't have access to electricity," he said. "More than 100 million children don't have access to education and a large share of students fortunate enough to be in school don't have access to quality education materials."

Nanotechnology used to make Solar Energy 25% more efficient

        Sol Voltaics has announced recently that by using nanotechnology, it is helping build solar cell modules to be 25% more efficient than the solar cells marketed in society today. If the company is able to deliver SolInk as how it is perceived in advertisements, then this could mean it would help make it excessively cheaper to introduce solar cells to a more broader set of customers.
        This nanotechnology is said to have the capacity to make solar power in residential areas and business environments more affordable, which can be necessary to increase adoption of solar energy and to help compete at the same cost of electricity produced from fossil fuel plants. This argument alone has helped Sol Voltaics raise $11 million in funding from public and private Scandinavian investors.
         CEO of Sol Voltaics, Dave Epstein, has claims that with nanotechnology, "we can increase the efficiency of energy capture, conversion and storage. There's no smoke and mirrors here." With two advances, it is made possible. The team, led by founder Lars Samuelson (a Lund University professor), created a technology known as Aerotaxy, which makes it cheaper to create nanomaterials. With this, they are able to create gallium arsenide nanowires that can serve as solar collectors and that they can integrate directly into solar wafers, known commonly as solar cells.
          As a material, gallium arsenide has been used in solar for years because of its high reliability and high efficiency at converting light into electricity. However, gallium arsenide is expensive to manufacture. SolInk dramatically reduces the cost by minimizing the amount of materials being used. In addition to SolInk's benefits, rivals such as Innovalight (bought by DuPont) can boost a solar panel's efficiency from 15% to almost 16.1% while SolInk is claimed to build the efficiency from 15% to almost 19% or from 20% to 25%. The theoretical limit in converting sunlight to electricity is approximately 27% to 29%.
         With Aerotaxy, it helps build nanomaterials by mixing vapors in the air in just a second. The active materials, then, bond to form larger, uniform structures while in motion. Nanowires are literally able to grow in the air. Also, with Aerotaxy, it helps generate tens of billions of nanowires per second on a continuous basis. "It's like cranking out nanowires with a popcorn popper instead of a craftsman. That's the makings of an affordable and scalable technology for mass production," said Epstein.
          According to Greentech Media, demand for solar is growing globally as we know it, with the total number of gigawatts expected at 29.8 in 2012 to 50.8 gigawatts in 2016. Epstein figures that solar is here to stay, since the sun is the only resource that will surely outlast fossil fuels, wind, and other clean energy sources in the run. "In spite of what you might hear, solar is a healthy market," said Epstein.
