Maximum Power Point Tracking
Maximum Power Point Tracking, frequently referred to as MPPT, is an electronic system that operates the Photovoltaic (PV) modules in a manner that allows the modules to produce all the power they are capable of.
PV Innovation - Here Comes The SolarQuilt
The design is simple yet truly effective in offering to the building owner an aesthetically pleasing, lightweight photovoltaic roofing system that rests on flat or low slope roofs, requires no roof penetrations, protects roofs from weather and UV radiation and produces cost effective solar electric energy.
Safer Lighting With Solar - Using The Sun For Emergency Preparedness
For emergencies there are all sorts of hand crank lights, solar flashlights, and low power LED flashlights. There's even a "shake-up" flashlight that uses a shaking motion of the hand to produce the needed power.
Utilization of Forest Residue Project
Power Energy Fuels, Inc. (PEFI) has the opportunity to assist the US Forest Service in converting forest residual (wood waste) into a useful commercial product.
What Does Kyoto Mean To Me?
Embracing change is the answer! As a nation, we need to look at this as an opportunity rather than an obstacle. This attitude and approach will lower our cost of living while creating a new market opportunity for green technologies. This opportunity can lead us to new industries and new jobs carrying our economy forward into a future world where we have learned to optimize, to adapt and overcome.
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.
