India + Renewable Energy = Positive Consequences

     India is growing in its expanding its clean energy opportunities, specifically solar, wind and other renewable energy projects, throughout India. In the last month, the Indian government had announced a $7.9 billion investment is to double its transmission capacity, which was designed to increase access to power from wind and solar projects. For instance, India's installed solar energy capacity has jumped from a mere 17 megawatts in 2010, when India's National Solar Mission was announced, to over 1.7 megawatts. Not only do these renewable energy projects increase India's energy supply, but they also help create much needed jobs.

     The Indian government and businesses around the country are making significant investments in renewable resources. The investment in transmission capacity and the next phase of the National Solar Mission are example policies to drive clean energy development. The motivations for these investments, in part, are to continue to power India's rapid economic growth and increase energy access by providing modern electricity to the nearly 400 million population in India without access to modern electricity.

Solar Power brings 16Mbps Broadband to Towns without Electricity

     White space networks have yet to revolutionize Internet access but they still have hope in creating a drastic impact in countries that have lack the consistency of Internet access. A new project of the power of white space networks is arising in Kenya as a solar-powered network brings Internet to people who aren't connected to an electrical power grid.
      The previous month, Microsoft, along with Kenyan government officials, deployed the network in various areas in Kenya. It is currently serving a health clinic in Burguret, a primary and secondary school in Male, a secondary school in Gakawa, and a library in Laikipia. The network is planned to be expanded to 20 other locations in the next coming months.
       Director of technology policy at Microsoft, Paul Garnett recalls that "down in the valley, nobody has electricity." However, some areas did have mobile Internet access, but "it's so expensive that nobody ever uses it," says Garnett. Electricity is not completely unavailable but it is said that it is scarce. For example, a school has electricity going into the principal's office but it is unavailable anywhere else.
       This is where solar power comes in; specifically, 4.5 kilowatt hours of energy per day are derived from 7 square-meter panels. "During the day the solar panel is providing enough to run the network and provide some charging capability, and then in evenings there is this battery backup that can continue to provide broadband access, plus you have excess capacity for overnight charging," Garnett said. "Think of the school scenario where you've got a computer lab that the kids can use during of the day, and drain down the batteries in the tablets during the day. And then in the evening you have a charging station where all the tablets are plugged in and can recharge overnight."

Brazilian-made Plastic Solar Panels

       Brazilians emphasize upon increasing their knowledge in terms of green technology research and have concluded to discover and develop plastic solar panels, which can help revolutionize power generation from such an amazing source of energy.

      This solar panel may seem like it is a thin sheet of plastic, but it is actually a solar panel covered with photovoltaic cells, which converts sunlight into electricity. Unlike other heavy and costly silicon-based solar panels commonly used in society today, this plastic solar panel was created by scientists at CSEM Brazil, a research institute in the southeastern state of Brazil, Minas Gerais.
      These solar panels are similar to transparent sheets of plastic with stripes where they printed with carbon-based organic polymers, in that they were made by incorporating organic photovoltaic cells into common polymers. The technology to produce the organic photovoltaic cells has been studied in Europe and the United States, but Brazil has made further development usage pertaining to the technology.
      "While the capacity for power generation is almost the same, its small size means that it can be given uses that are impossible for silicon panels," said Tiago Maranhao Alves, chairman of CSEM Brazil and physical engineer who directly participated in the research. This material is able to power electrical components of automobiles and in electronic devices such as mobile phones, wireless keyboards and mice. "A panel with a surface of two or three square feet meters can be sufficient to generate the energy needed in a house lived by a family of four," Alves also remarked.
       Transportation is also an advantage of the solar panels, compared to the common silicon-based panels. "Because they are easy to transport, logical costs are lower. In addition, people can take them with them when they move to a new home," Alves noted. The plastic solar panel is able to be used in covering buildings and venues like airports and sports stadiums, avoiding the need to set aside an area for installation of the silicon panels.

Mexico is Increasing its Solar Power!

       Driven by wealthy households and first large-scale power plants, Mexico has the potential to increase its photovoltaic capacity nearly tripling this year. Alvaro Lenz-Herrera, president of Asosiacion Nacional de Energia Solar, has commented in an interview that solar installations may double estimating from 30 megawatts to 60 megawatts, in which 30 megawatts are currently operating and may triple if its state-owned utility power grid, Comision Federal de Electridad (CFE), calls for a tender for increasing photovoltaic capacity.

Mexico initially desires to increase the awareness of solar power energy towards their generation and to reach their goal of having 35% of their power generating from clean, renewable energy sources by the year 2026. The country offers tax incentives in terms of solar power energy projects as well as providing possible long-term relationships with their power grid (CFE).

Photovoltaic capacity is expected to increase by the result of the falling solar panel prices and low system costs, which are claimed to be estimating 20% cheaper than solar power energy projects funded in the United States. Alvaro Lenz-Herrara also remarks that he predicts growth towards solar energy will increase in 2014 and 2015.
