The other consists of pro-growth "green" greens, who see riches in solar energy and battery driven cars.
It seems straightforward, but it is only the improved efficiencies in solar cell and battery technologies, even over the last year, that has made this at all possible.

Demonizing the alleged global-warming industries may play well with a key Obama constituency, but it has come at the expense of taxpayers as bankruptcies pile up with wind, solar, and battery firms.
The design makes use of solar panels to create a pergola, and the battery would store unused solar electricity for use at night or during a blackout.

We can see it in the wind farms and solar plants and advanced battery plants that are opening all across America.
Instead of selling individual units, they would offer a low-power system that relied on a solar cell or car battery in remote areas without grid electricity.
Instead of selling individual units, they would offer a low-power system that relied on a solar cell or car battery in remote areas that didn't have grid electricity.
Now the battery is easily removable and can be charged in all sorts of ways, like clipping it into a charger powered by a car battery or solar panel.
Networks are riddled with circuit breakers that prevent electricity from flowing backward to the substation when voltage drops--the moment when utilities need solar cells and basement battery packs to support the grid.
All the park managers want to do is create a microgrid with a few solar panels and a battery pack to meet a few humble power needs with no connection to the larger grid.
FORBES: D.C. Park Reveals the Gap Between Microgrid Promise and Reality
Such solutions are clearly some way off commercial development, but with Apple rumored to be designing its hotly-anticipated iWatch around a power source based on kinetic and solar power, a battery-free world isn't such a distant dream.
The Spark Solar Case and V39 External Battery are available now on www.voltaicsystems.com and with select retailers.

In the medium term, solar power combined with improved battery storage systems will make a difference, as will military vehicles with hybrid electric engines.
These devices transform the direct current generated by a solar panel or electric car battery into the alternating current you expect from a wall socket.
Besides the built-in battery, the solar panel seems the most feasible.

It involves a centralised, village-level system with a large solar panel that charges a car battery.
In this demonstration, a solar panel feeds power to a battery, which then feeds it to a laptop.
There have been issues with using alternative power sources like wind and solar as they constantly need a battery backup as these sources are not available all the time.
