By the middle of this week we will have eleven hours of daylight, and we are just about a month away from the vernal equinox.
In honor of the sun, here is some good news on the solar energy front from Scientific American…
The energy benefits of solar photovoltaics will only improve as the technology continues to boost its efficiency at converting sunlight to electricity or proves to last longer than the 30 years anticipated by manufacturers. “There is no reason for this not to last a lot more than 30 years,” Fthenakis says.
If solar energy begins to power its own productionâ€”a so-called PV breeder cycle, in which PV-generated electricity goes to produce more PV cellsâ€”the outlook is even sunnier. “I think 30 percent of the energy consumption in the [manufacturing] facilities is easily met from the land they have available [on] the roof and in the parking lot,” Fthenakis says.
Wow! Canâ€™t you just feel the singularity coming? Of course, with all that energy production, weâ€™ll need some big batteries to store it. Good news there too…
VRB will start mass production this year of a longer-lasting rival to the lead acid battery currently used to store energy for example produced by solar panel, Hennessy said.
Low carbon-emitting renewable energy is in vogue, driven by fears over climate change, spiraling oil prices and fears over energy supply and security.
While the supply of the wind and sun far exceeds humanity’s needs it doesn’t necessarily match the time when people need it: the sun may not be shining nor the wind blowing when we need to cook dinner or have a shower.
Soaring production of solar panel and wind turbines is now spurring a race to develop the winning energy storage technologies which will drive the electric cars and appliances of the future.
Wouldnâ€™t it be great to tell the rest of the world, especially those nations that don’t like us, that they can keep their oil, we donâ€™t need it. Remember when a young, visionary and daring president led our country to put a man on the moon? Now we just need a battery. We can do it. Now is no time to build more nuclear power plants — thatâ€™s so 20th century. We need to invest in solar.
