Wind Farms | Wind Power | Wind Turbines

Though our scientists may claim that they are inventing something new by using wind as a source of generating energy, the truth is that wind is being used for centuries for this purpose. An example of this is an article published in 1838, which clearly shows that even in those times, wind was considered an […]

The Sierra Club interviews Envision Solar’s new COO, Desmond Wheatley, about he benefits of their soalr trees – used for charging elctric vehicles and providing a “low-tech” solution for providing shade in parking lots.

Read the story here:

Your “Solar Trees” address some of the criticisms out there that it takes a long time to power an electric car versus a two-minute trip to the gas station with a traditional gas guzzler. Considering how long cars sit in parking lots, this technology powers up cars while they sit dormant.Absolutely. It’s fantastic to be able to put to rest certain issues, such as the electric car’s range. But there’s so much more to it. For example, when it comes to solar covered parking lots, we know that employees like to get early to spots in the shade. About 80 percent of what electric vehicles first take in goes to cooling a battery to get it to an optimal temperature before it charges. If this car is parked in the sun, you have to use energy just to get the battery cooled before you can charge. So this low-tech aspect includes a shaded array that makes it even easier to charge.Also, this is a grid offset solution. Electric cars are great and we applaud them. But it’s nowhere near as good as electric cars powered by clean, solar energy. Electric cars are only as clean as the energy that charges the battery.Another thing is that this is good for the electrical grid. New electric cars are like plugging in new houses into the grid. We offset that because we make the electricity where it’s used. It’s a no-brainer. A win-win-win.

Energy Industry | Wind Farms | Wind Power

Wind energy currently meets a mere 1.5% of global electricity generation. But scientists foresee a lot of potential in this alternative energy source. Asian countries are also trying to embrace clean and green energy. South Korea is going for an ambitious off-shore wind farm amounting to $8.3 billion. This project will be executed at the […]

If you have opted for a wireless keyboard you know the importance of rechargeable batteries and a wall charger. Although it is easier to charge the batteries after a while it becomes an annoyance to change them repeatedly. Now Logitech is coming out with a solar-powered keyboard that will be free of such hassles. No […]
