And that's not all. We reported recently on this site on the solar powered car making its way around the world. We also covered the concept of solar roads to capture usable energy. We even reported on a sail boat powered with a solar sail. Now the BBC reports   that the U.S. military has held a test run in Arizona of a UK-made solar plane, the Zephyr-6. The plane flew for more than three days, running at night on solar charged batteries. The more than 83 hour non-stop flight was the longest of any unmanned aircraft.

Does it make sense to solar power everything? It leads to many small, and relatively expensive installations. Wouldn't it be more effective to go for a battery & plug-in concept where possible. One would loose the inflight recharging of the solar airplane, but for everything else, the plug-in concept probably provides benefits.

A new state energy plan released Tuesday calls for more conservation, more use of renewable sources such as solar and wind power, a tougher New York building code and a disclosure requirement for a building's utility usage when it's sold. Gov. David Paterson said the plan he accepted from the State Energy Planning Board provides the blueprint for a continuing transition to a clean energy economy over the next decade. Initiatives for 2010 include the building sale disclosure and removing loopholes that have limited the effectiveness of the state's energy code. Both require legislative action. Others include procuring 100 megawatts more of solar energy statewide and requesting bids for an offshore Long Island wind project.

CSEM, the Swiss Center for Electronics and Microtechnology, has signed a contract with the government of the Emirate of Ras Al-Khaimah (RAK) in the United Arab Emirates (UAE), to develop a prototype of a “Solar Island”. The aim of the project is to validate a concept for the large-scale transformation of solar energy into hydrogen and electricity at very low cost. It is funded by 5 mio US$ by the Gouvernment of Ras al Khaimah. The plan is to build large “Solar Islands” floating in the sea. These giant floating islands will be fitted with solar panels which will convert solar energy into electricity and/or hydrogen. A prototype of such a solar island, equipped with thermal solar panels, is to be built and tested in the desert of the United Arab Emirates.

photovoltaics lighting scavenging

shared by Hans De Keulenaer on 10 May 13 - No Cached

Solar panels capture energy from light and convert it to electricity.   This is the most visible form of energy harvesting, but it is hardly the only one.  Energy harvesting captures energy lost as heat, light, sound, vibration, or movement.  Devices that harvest or scavenge energy can capture, accumulate, store, condition, and manage this energy into electricity for consumption.  That’s important, because our existing electricity infrastructure is extremely wasteful in its use of energy.  For instance, today’s technologies used in electricity generation are not energy efficient.  Traditional gas or steam-powered turbines convert heat to mechanical energy, which is then converted to electricity.  Up to two thirds of that energy input is lost as heat.  Those old incandescent bulbs (technology invented by Thomas Edison in 1879) were real energy losers too.  Ninety percent of the electricity flowing into incandescent bulbs ends up as waste heat. That’s lost energy, which is why smart federal legislation banned incandescents in favor of more energy efficient sources of lighting starting in 2012.

"t is a crucial, if geekish, point: Wind and solar power are NOT intermittent, they are VARIABLE. If someone talks about problems with the intermittencies of wind and solar energies, it is out of ignorance or to intentionally discredit them. Obviously, the sun does not always shine and the wind does not always blow but those things can be scheduled and forecasted and are no reasons whatsoever not to keep building wind power and solar energy as fast as is humanly possible. The Western Wind and Solar Integration Study, from the National Renewable Energy Laboratory (NREL) of the U.S. Department of Energy (DOE), says transmission system tools are now available that would allow the Mountain West and Southwestern states to get 35% of their electricity from wind and solar energies by 2017. All it will require, aside from the building of the wind and solar production capacity, is a change in the WestConnect group of grid operators' standard operating procedures."

Fred Pearce has framed his latest opinion piece in Yale Environment 360 as one about Europe fiddling around with its climate change commitment (with German Chancellor Angela Merkel as lead violin), while the US is poised to reengage with the world under the Obama administration. What it's really about though is what the US would need to do to take that lead, and it all has to do with renewable energy. Though some of this may be recap for avid TreeHugger readers, it's worth repeating: Stephen Chu Appointment a Good Sign Beyond his stated commitment to dealing with climate change during the campaign, Pearce indicates that the appointment of Stephen Chu as energy secretary is the real sign that the US could soon lead the renewable energy/climate change race. Not only has he done pioneering research on solar power, energy efficiency and cellulosic biofuels at the Lawrence Berkeley National Laboratory, he's also an advocate of a nationwide expansion of the electric grid to bring renewable energy from where it's most easily generated (west of the Mississippi) to where the greatest demand is (east of the river).

Solar energy can be utilized in various ways - to provide electricity, mechanical power, heat and lighting. Passive solar heating and cooling can save substantial electricity bills. Design of a building is very important for tapping passive solar energy. The building and windows are designed in such a way that they carefully balance their energy requirements without additional mechanical equipment. Solar benefits are utilized through windows and pumps, and fans are used minimally.

The Commission of the Economic Community of West African States (ECOWAS) works towards a voluntary commitment to the Sustainable Energy For All Initiative of the UN Secretary General presented at the Rio+20. In a regional workshop, held from 25 to 27 June 2012 in Dakar, Senegal, the Directors of the ECOWAS Ministries of Energy agreed on the main targets and pillars of a regional renewable energy and energy efficiency policy of ECOWAS. The policies aim at the following objectives: Around 30% of the electricity consumption in the ECOWAS region will be saved through demand and supply side efficiency improvements by 2030. The share of renewable energy (incl. large hydro) of the total installed electric generation capacity of ECOWAS will increase to 35% in 2020 and 48% to 2030. The share of new renewable energy such as wind, solar, small scale hydro and bioelectricity (excl. large hydro) will increase to around 10% in 2020 and 19% in 2030. These targets translate to an additional 2.425 MW renewable electricity capacity by 2020 and 7.606 MW by 2030. To provide universal access to energy services it is envisaged that around 75% of the rural population will be served through grid extension and around 25% by renewable energy powered by mini-grids and stand-alone systems in 2030. By 2020 the whole ECOWAS population will have access to improved cooking facilities either through improved stoves or fuel switching to other modern forms of energy such as LPG. The share of ethanol/biodiesel in transport fuels will increase to 5% in 2020 and 10% in 2030. By 2030 around 50% of all health centers, 25% of all hotels and agro-food industries with hot water requirements will be equipped with solar thermal systems.

The Times has a story in the "deserts of gold" genre, confusing solar PV (panels) with concentrating solar thermal power - Solar panels in the Sahara 'could power the whole of Europe'. There is a new twist to the story now though, with North Africa's wind power potential also being touted. All of Europe's energy needs could be supplied by building an array of solar panels in the Sahara, the climate change conference has been told. Technological advances combined with falling costs have made it realistic to consider North Africa as Europe's main source of imported energy. By harnessing the power of the Sun, possibly in tandem with wind farms along the North African coastline, Europe could easily meet its 2020 target of generating at least 20 per cent of its energy from renewable sources.

It seems cruelly ironic that tapping into Southern Nevada's vast solar energy potential could slowly drain our desert. Traditional solar thermal power plants that use wet cooled technology require millions of gallons of water over time in the process of converting solar rays into clean, renewable power for our community. Southern Nevada received some good economic news last month when Solar Millennium, a division of one of the world's top solar power generators, announced new plans to use a "dry-cooling" system on two proposed solar power plants in Amargosa Valley, 90 miles northwest of Las Vegas. This dry-cooling system will use 90 percent less water than previously planned.
