Green Tip

ENERGY STAR electronics

No dorm room is complete without an ENERGY STAR qualified entertainment system, right? With all that work, everyone needs some time to decompress and with ENERGY STAR qualified TVs, DVDs, Blu-Ray Players, and speakers, you can really relax--not only from your work, but also knowing that your electronics are using less energy, even when they are off. That's because ENERGY STAR specifications for TVs, and other electronics, are more efficient both when the TV's off (in standby mode), and when the TV's on (in active mode). But you will never miss that extra power since even the latest and greatest in TV technology can earn the ENERGY STAR. What you will notice is how good you feel helping the environment. If each TV, DVD and home theatre system purchased in the U.S. this year had earned the ENERGY STAR, we would prevent more than 6 billion pounds of greenhouse gas emissions per year, equivalent to the emissions from 570,000 cars!

What is Green Power?

What is Green Power?

Renewable energy resources such as solar, wind, geothermal, biogas, biomass and low-impact hydro generate GREEN POWER.

Solar Power

Solar power (also known as solar energy) is Solar Radiation emitted from our sun. Solar energy has been used in many traditional technologies for centuries, and has come into widespread use where other power supplies are absent, such as in remote locations and in space.

Wind Energy

Wind power is the conversion of wind energy into more useful forms, usually electricity, using wind turbines. Most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator. In windmills (a much older technology), wind energy is used to turn mechanical machinery to do physical work, such as crushing grain or pumping water.

Wind power is used in large scale wind farms for national electrical grids as well as in small individual turbines for providing electricity to rural residences or grid-isolated locations.

Wind energy is plentiful, renewable, widely distributed, clean, and reduces toxic atmospheric and greenhouse gas emissions if used to replace fossil-fuel-derived electricity.

Geothermal

Geothermal power is the use of geothermal heat to generate electricity. Geothermal comes from the Greek words geo, meaning earth, and therme, meaning heat.

Biogas

Biogas typically refers to a (biofuel) gas produced by the anaerobic digestion or fermentation of organic matter including manure, sewage sludge, municipal solid waste, biodegradable waste or any other biodegradable feedstock, under anaerobic conditions. Biogas is comprised primarily of methane and carbon dioxide.

Biogas can be used as a vehicle fuel or for generating electricity. It can also be burned directly for cooking, heating, lighting, process heat and absorption refrigeration.

Biomass

Biomass, in the energy production industry, refers to living and recently dead biological material which can be used as fuel or for industrial production. Most commonly, biomass refers to plant matter grown for use as biofuel, but it also includes plant or animal matter used for production of fibres, chemicals or heat. Biomass may also include biodegradable wastes that can be burnt as fuel.
