GEOTHERMAL IS NOT WHAT MANY PEOPLE THINK IT IS
What: No "Old Faithful" in your back yard?
GREEN ROOFING OPTIONS AND ADVANTAGES
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.
HOW TO INFORM PEOPLE AWAY FROM SUSTAINABLE
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.
LIGHTS OUT FOR INCANDESCENTS & HALOGENS
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
RAINER WISCHINSKI - SPINWAVE SYSTEMS
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.
ROGER COX - THE EVOPOD
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.
SOLAR PHOTOVOLTAICS MARKET POTENTIAL
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?
SOLAR THERMAL AND EVACUATED TUBE TECHNOLOGY
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 GREEN DATA CENTER
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 HEADING FOR $1 PER WP
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.
TIOGA ENERGY REPORT - SOLAR PPA
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.
WASTE-TO-ENERGY (WTE) CONVERSION
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.
Better Wind Turbine Transmission
This article is intended as a suggestion for manufactures of, and users of large wind turbines. Users have noted reliability problems mostly due to the use of a mechanical gear transmission required to transform the relatively slow rotational speed of the large turbine hub to the required shaft speed of the synchronous alternator.
Care Home Project Gives the Green Light
A new eco-friendly £5 million private care home in Sussex has elected to use solar energy as the primary source for both its heating and lighting. Eric Hawkins, MD and founder of Powertech Solar, describes how the project has provided an ideal opportunity to demonstrate the energy saving potential of the company's Suntech Solar Commercial range.
EarthToys Interview - Living Off The Grid
I think it's feasible to be off the grid anywhere you have access to sun, wind, or water for power. However, the city planning department may have other ideas. I know a couple in southwest Oregon whose urban homestead was off-grid on a city lot for many years, but they had a community that was supportive of renewables.

SolarEdge Technologies - EV Charging Single Phase Inverter
The SolarEdge PV inverter combines sophisticated digital control technology with efficient power SolarEdge's EV charging single phase inverter offers homeowners the ability to charge electric vehicles up to six times faster than a standard Level 1 charger through an innovative solar boost mode that utilizes grid and PV charging simultaneously. This product is the world's first EV charger with an integrated PV inverter. Reducing the hassle of installing separately a standalone EV charger and a PV inverter, the EV charging inverter eliminates the need for additional wiring, conduit and a breaker installation. By installing an EV charger that is integrated with an inverter, no additional dedicated circuit breaker is needed, saving space and ruling out a potential upgrade to the main distribution panel. Whether you own an EV now or just want to be EV-ready, future-proof your home with SolarEdge.
