Solar Dynamics Announces Portable Personal Power System

Solar Dynamics, Inc., a manufacturer of portable solar power systems, announced today the availability of The Cub', a lightweight, portable power source that provides DC and AC electricity for small electronic devices and recharges itself through a 5 watt thin film solar module.

Distributed Generation (DG) Technologies

Distributed Generation (DG) technologies have the potential to increase the reliability and quality of worldwide power in the coming decade but need continued active support from the US government.

World's largest thin-film solar cell manufacturing machine.

United Solar Systems Corp announced the official inauguration of the world's largest thin-film solar cell manufacturing machine and related assembly equipment at its Bekaert ECD Solar Systems (its joint venture with Bekaert) facility in Auburn Hills, Mich.

U.S., other rich countries balk at widening solar, wind power

The United States, Saudi Arabia, and other wealthy nations at a U.N. summit worked Tuesday to water down proposals to rapidly expand the use of clean, renewable energy technologies around the globe.

Automated Window Shading

As compared with passive switchable glazing technologies such as photochromic or thermochromic -- which merely react to environmental conditions such as ultraviolet radiation or temperature -- SPD technology offers the user control over the amount of light transmission and much faster switching speeds.

Automating HVAC Registers

To make the motorized registers, I'm using standard units purchased at a local hardware superstore, and the small servo motors were purchased from a local hobby shop that deals in Remote Control cars, planes and boats. All that's needed is a simple circuit to control them.

Can Home Automation Save You Money On Your Electrical Bill?

Ideally, a home energy controller would be programmed to calculate when loads should be turned on or off. It should also be designed to look at alternate solutions such as closing the window blinds before turning on the air conditioner to cool a room. The controller has to strike a balance between energy savings and comfort and convenience to the homeowner. The system should be almost invisible to the homeowner. If it isn't, it will soon be disabled.

Managing Energy Usage Among Residential Customers

The EMi thermostat is connected to an external modem that accesses the Internet via the regular telephone supply of a home or small business customer. When the utility company wishes to initiate a supply curtailment, it sends a call to the modem using a distinctive ring pattern that will activate the modem. The modem then calls a central utility curtailment dispatch station, from where it downloads the new settings to the thermostat.

The Residential Gateway As Energy Manager

In a survey of high-end entertainment households, when asked about the usefulness and interest of PC-based control services, respondents ranked energy management as the most attractive service option with 54% indicating that they had a strong interest in such a service. Utilities are aware and energized by this new demand, and as telemetry services become more widely available, Parks Associates believes consumers will be receptive to such services.

Watts Up!

A commercial business owner in Southern CA, utilizing several stores in a strip mall, is currently paying $2,500.00 per month for electricity. He/she is being warned of a 78% increase by 2002, which would put his/her costs at $4,450.00 per month. This considerable increase in overhead will spawn a definite increase in his/her products and services to customers. In order to remain competitive, a business owner will be forced to find solutions to save energy on a long term basis.
