ZigBee Smart Energy is a standard, easy and affordable way for communicating energy-related information, such as price, over ZigBee wireless home area networks. It is a global, open standard that facilitates the creation of interoperable energy-related devices from multiple vendors to monitor, control and automate the use of energy.
Ford, Bell, Edison and the Wright Brothers would not be allowed to create their innovations today. Their businesses started too small; their ideas were "unproven." Issues with permits, insurance, rights of way would have killed their ingenuity. In a free market, ingenuity has a small chance of churning into commercial success. In a planned economy ingenuity is doomed.
At present there are globally 439 nuclear power reactors in 31 countries with an installed electricity net capacity of about 372 GW in operation, generating approximately 16 per cent of the world's electricity.
What: No "Old Faithful" in your back yard?
Working in conjunction with a well-insulated attic, environmentally friendly roofing can go a long way to keep the home's heating and cooling system functioning optimally. If it's about that time to renovate your roof, you've got a big and important project on your hands. That said, here are some things to look out for when planning for a green roof.
It is much easier to stress the unreliability of RE if you ignore the fact that wind and sun were never meant for baseload energy production, and that hydro, biomass, geothermal, etc. are continuous, storable and in fact easier to turn up/off than nuclear.
It's clear that all large-scale lighting applications, from businesses to schools, stand to benefit from LEDs. Whether it's T8 fluorescent replacement, halogen replacement, or large-scale incandescent floodlight replacement, the benefits make the upgrade a no-brainer
Spinwave Systems develops and markets wireless EMS. This includes wireless sensors for temperature, relative humidity and motion (occupancy), wireless utility meter interfaces for electric, gas and water meters and wireless switches to control equipment and lighting loads.
Independent studies carried out in the UK have predicted that conservatively about 7% of the UK's present electricity usage could be produced from tidal stream energy sources. Evopod has been developed to extract energy from the deeper water sites where the water depth is greater than 35m to 40m.
The three leading countries -- Germany, Japan and the USA -- represent almost 89% of the total worldwide PV installed capacity. Could these countries' renewable energy political decisions provide a model for the rest of the world?
The interesting thing is that despite the fact evacuated tubes have better performance throughout the day because of IAM, are more economical due to ease of installation, and are capable of reaching higher temperatures, the technology has not received the recognition it deserves since the majority of the publicity we currently see focuses on PV.
The average power consumption per server quadrupled from 2001 to 2006, while the average number of servers doubled and is expected to grow another 50% by 2010. This rapid growth has resulted in data centers typically consuming up to 100 times more energy per square foot than a typical office building.
Thin-film solar cells are cheaper than traditional solar panels, such as those made of polycrystalline silicon, but the yield is lower. However, the combination of these properties is promising according to the Thin-Film Future conference organized recently by SolarPlaza in Munich. An impression of the heavily attended gathering.
In today's marketplace, energy has become a strategic issue. Organizations of all types, including corporations, government agencies and non-profits, are evaluating where they get their power, how much they use and what they're spending for it.
Generally, the greater the economic prosperity and the higher percentage of urban population, the greater the amount of solid waste produced. Reduction in the volume and mass of solid waste is a crucial issue especially in the light of limited availability of final disposal sites in many parts of the world.

The Darfon G320 is the microinverter solution for today's high-power solar modules. The G320 handles 60- and 72-cell modules up to 350W DC and outputs up to 300W AC. The G320's 3-phase configuration accommodates the electrical distribution systems of most commercial buildings and to reduce, if not eliminate, the need for expensive transformers. The G320 comes in four voltage/phase configurations, so it can be installed in residential, commercial or utility applications.
