For homeowners interested in reducing their personal carbon footprint through solar power but wanting to start off on a smaller scale than a whole-house option, an exciting, energy-saving solution will be available soon from heating and air conditioning leader Lennox Industries. Expected to be available in 2009, Lennox' new SunSource™ system is the industry's first integrated, solar-assisted residential heating and cooling system - and it uses just a single 190-watt solar panel. Featuring a patent-pending design, the innovative system is currently in full operation at multiple test sites throughout the country. The single 190-watt solar panel provides power to assist the fan motor that moves air across the outdoor coil, a key part of any home comfort system. Read more.
In a typical household, over 12 percent of the power bill goes on the small amounts of power consumed by devices in standby mode. Are you a gamer? Well ratchet that figure up considerably further. TrickleStar have a device to save that waste. The TrickleStar™ Universal Standby Power Saver reduces the standby energy consumed by PC and TV Peripheral equipment. The product has inbuilt current sensing circuitry to sense when a PC or TV is on or Off. When the PC or TV is on the product will switch On all peripheral devices. Conversely when the PC or TV is Off, the product will switch Off all peripheral devices. The product is easy to install and provides simple automation to reduce wasteful standby energy consumption.

The Power Electronics team from Swansea University's School of Engineering has developed one of the world's most advanced Smart Electricity Meters. The Smart Meter is to be the focal point for a consumer's personal energy queries. It monitors their energy consumption, giving information not just through a traditional power reading, but in a user-friendly way by displaying animated graphics of money on a large clear screen on the meter. It also goes one step further than most other potential Smart Meters in that it monitors individual power circuits in the home, including upstairs lighting, downstairs lighting and kitchen sockets. The team believes there is also the possibility to monitor individual appliances when the technology is adopted further. The presentation of consumption information is complemented by the ability to show power generated from micro-renewable technologies in a 'plug and play' manner, similar to the wind turbine currently commercially available, and generic solar panels. This is an effort to provide a simple, easy to set up method for people with no expertise in Power Electronics. Read more .
The Karma will do 0-60 mph in 5.8 seconds with a top speed beyond 125 mph (200 km/h) but only has a 50-mile range per charge on lithium-ion batteries. The driver will be able to select between two modes of driving. The first mode is Stealth Drive, which is the quiet economy mode for optimal relaxed and efficient driving. Evidently, the car moves so quietly the company will be offering optional interior and exterior speakers with a menu of "car noises." I kid you not. By flipping the second paddle behind the steering wheel, the car will switch to Sport Drive, which will access the full power of the vehicle. To be offered fourth quarter next year, the Karma will be built in Finland and priced at $80,000. http://www.fiskerautomotive.com/ . More photos http://www.fiskerautomotive.com/vehicles/downloads/
The wheelchair's fuel-cell system is a 24V 250W PEFC Air Cooling External Humidifier. It drives at a max. speed of 6km/h and the driving range is 10hours, 60km (H2 Storage 190g/4 canisters) and 5hours, 30km (H2 Storage 100g/2 canisters). With the Japanese population aging rapidly, the fuel-cell wheelchair and cart applications have a bright future. Promoted as "Eco" fuel-cell powered means turning the "silver market" into green.

Starting next year drivers in the Los Angeles and New York areas will be able to lease a fleet of 500 all-electric Coopers from BMW's Mini division. The Mini E, as it's called, will be able to travel 150 miles on a single charge with a top speed of 95 miles per hour. The Mini E will be a two-seater. The space usually taken up by back seats in a gas-powered Mini will be taken up by lithium-ion batteries. While the initial start may be quick, the Mini E will accelerate up to 62 miles (100 kilometers) per hour in 8.5 seconds, which is about average for a modern car. CNN report.
Energy inefficiency is not easily noticed in facilities. Aging infrastructure, high energy and maintenance costs are all proxies for energy inefficiency in facilities. Typically if an energy audit has not been done at a facility in the last five years, and is accompanied by some of the conditions mentioned above it is a good candidate for an energy action plan.
You've got some money saved and going solar crossed your mind. But you'd rather have new floors or walls, or invest in the little addition you always wanted. Why not do both?
Middle Eastern oil sheiks move over. There's a new kid on the energy block!
The livestock industry is a vitally important contributor to the economy of any country, regardless of the degree of industrialization. Animal manure is a valuable source of renewable energy; additionally, it has soil enhancement properties.
Plug-in cars appear to be a natural companion to wind power. Presumably car owners would plug their vehicles in at night to recharge. Evening is typically a windy time, so turbines would whir, pushing power into the grid to feed the cars.
PARKING LOTS IN THE AGE OF SUSTAINABILITY CREATING A LANDSCAPE OF CLEAN ENERGY, BEAUTY, AND ELECTRIC
By activating vehicle parking areas with pleasing shade structures, communities will achieve massive deployment of highly visible renewable energy projects that create clean energythrough sustainable design.
With typical tankless heaters you end up with a tub full of tepid water. If you try to fill it more slowly to get it hotter, it takes so long to fill that it cools off before you get in anyway. So if you like to soak away in a hot tub, you better make sure you get a big enough heater to handle the job.
Over here in the United States, UTC Power has racked up several significant high profile fuel cell installations with more coming down the pipeline.
The oil and gas industry were provided a $17 billion tax credit from 2007-2011 in the latest energy bill passed last December. That's $3.4 billion in tax credits for each of five years.

The addition of energy storage to an existing or new utility-scale PV installation allows system owners and operators the opportunity to capture additional revenues. Traditional storage plus solar applications have involved the coupling of independent storage and PV inverters at an AC bus or the use of multi-input hybrid inverters. An alternative approach - coupling energy storage to PV arrays with a DC-to-DC converter - can help maximize production and profits for existing and new utility-scale installations. DC-Coupled Utility-Scale Solar Plus Storage leads to higher round-trip efficiencies and lower cost of integration with existing PV arrays and at the same time, opens up new revenue streams not possible with traditional AC-coupled storage, including clipping recapture and low voltage harvesting, while being eligible for valuable tax incentives.
