Farmers in Japan can now generate solar electricity while growing crops on the same farmland. In April, the Ministry of Agriculture, Forestry and Fisheries (MAFF) approved the installation of PV systems on existing crop-producing farmland. Previously solar generation on farmland, productive or idle, was prohibited under the Agricultural Land Act.
This co-existence or double-generation is known as “Solar Sharing” in Japan. The concept was originally developed by Akira Nagashima in 2004, who was a retired agricultural machinery engineer who later studied biology and learned the “light saturation point.” The rate of photosynthesis increases as the irradiance level is increased; however at one point, any further increase in the amount of light that strikes the plant does not cause any increase to the rate of photosynthesis.
We typically see photovoltaic panels up on roofs, as they're broad, open surfaces that receive a lot of sunlight. You know what else spends a lot of time in the scorching sun, though? Sidewalks. With that in mind, a team at Washington DC's The George Washington University has created what is claimed to be "the first walkable solar-paneled pathway in the world."
Some of the most vulnerable places in the world to live in the face of climate change are islands. Rising sea levels, contaminated ground water, and increasing severity of storms are just some of the many threats to island communities. Many island residents also pay extremely high energy prices, due to limited domestic resources and the need to import fuel long distances. Switching to renewable energy can not only decrease fuel expenditures for many island populations, but can also show the world what can be done in the face of climate change.
WASHINGTON, D.C. – SEIA President and CEO Rhone Resch released the following statement today after California Gov. Jerry Brown signed landmark energy legislation AB 327 into law:
RICHMOND, Va. (AP) - Virginia regulators are considering Dominion Virginia Power's proposed plan to increase the use of solar power.
ROCKFORD, Minn. -- David Schmidt has been intrigued by the idea of generating power from the sun for a long time, but he had never taken the next step.
In the cleantech sector, pretty much everyone knows the acronym RPS, for Renewable Portfolio Standards. Since the first RPS policy in the U.S., implemented in Iowa in the late 1990s, 30 states have passed similar policies to promote the installation of renewable energy projects and expedite penetration (overcoming the ambivalence or outright opposition of utilities) of renewable energy in electric power supply.
"For most of these states, they're looking at it for economic development and job creation," Ghassemi said, underscoring the reasons why solutions such as cost incentives and utility quotas haven't helped states like New Mexico catch up to California and New Jersey, an unlikely solar leader.
The big question for any homeowner considering installing solar power is a simple one: How quickly will the system pay for itself?
The short answer: It depends on where you live.
