Hydroelectricity is the term referring to electricity generated by hydro power; the production of electrical power through the use of the gravitational force of falling or flowing water.
Solar Energy
Radiant energy emitted by the sun.
Wind Energy
Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electrical power, windmills for mechanical power, wind pumps for water pumping or drainage, or sails to propel ships.
Radiant Energy
Energy that is transmitted in the form of (electromagnetic) radiation; energy that exists in the absence of matter
Geothermal Energy
Energy derived from the heat in the interior of the earth
Biomass Energy
Natural Resources
Compressed Natural Gas
CNG is a fossil fuel substitute for gasoline, Diesel fuel and propane/LPG. Although CNG's combustion does produce greenhouse gases, it is widely considered a more environmentally "clean" alternative to conventional fuels.
Nuclear Energy
power obtained by harnessing the energy produced by waves at sea.
Tidal Power
Tidal power, also called tidal energy, is a form of hydro power that converts the energy of tides into useful forms of power - mainly electricity. Although not yet widely used, tidal power has potential for future electricity generation
a tree of the forest, especially a timber tree, as distinguished from a fruit tree.
A colorless, transparent, odorless, tasteless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.
Hydrogen Fuel
Hydrogen fuel is a zero-emission fuel which uses electrochemical cells, or combustion in internal engines, to power vehicles and electric devices. It is also used in the propulsion of spacecraft and can potentially be mass-produced and commercialized for passenger vehicles and aircraft.
Renewable Resources

Wave Power
Power obtained by harnessing the energy produced by waves at sea.
Non-Renewable Resources
Minerals Metallic
Minerals with a high specific gravity and metallic luster, such as titanium, rutile, tungsten, uranium, tin, lead, iron, etc. In general, the metallic minerals are good conductors of heat and electricity.

Minerals Non-Metallic
of or relating to a nonmetal.
Petroleum or crude oil is any naturally-occurring flammable mixture of hydrocarbons found in geologic formations, such as rock strata. Most petroleum is a fossil fuel, formed from the action of intense pressure and heat on buried dead zooplankton and algae.

Natrual gas
flammable gas, consisting largely of methane and other hydrocarbons, occurring naturally underground (often in association with petroleum) and used as fuel.
A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms. Examples of this carbon fixation occur in plants and microalgae. These fuels are made by a biomass conversion
Issues of Our Environment
Go Green-Recycle
Q. Carrying Capacity of the earth and where are we now?
A. August 20 is Earth Overshoot Day 2013, marking the date when humanity exhausted nature’s budget for the year. We are now operating in overdraft. For the rest of the year, we will maintain our ecological deficit by drawing down local resource stocks and accumulating carbon dioxide in the atmosphere.
Q. What countries “Recycle” what and how is it used?
A. UK households produced 30.5 million tonnes of waste in 2003/04, of which 17% was collected forrecycling (source: defra.gov.uk). This figure is still quite low compared to some of our neighbouring EU countries, some recycling over 50% of their waste. There is still a great deal of waste which could be recycled that ends up in landfill sites which is harmful to the environment.
Q. What efforts (show EXAMPLES) are being done by “Going Green”?
A. 1. Save energy to save money. 2. Save water to save money. 3. Less gas = money
Q. Where are the Landfills? In WA. State.
A. Serving Central Washington, the Greater Wenatchee Regional Landfill and Recycling Center provides communities and businesses with professional disposal services that are safe and convenient.
Q.Why do we produce things that cannot be REUSE?
A. Waste reduction starts at the supermarket. By making slight alterations to your shopping list you can significantly reduce the amount of waste created in and around the home.Many of the items that you would normally consider as rubbish could be used for other purposes. So instead of throwing items away, reduce waste by using them for other roles.
Carbon Credit
a permit that allows a country or organization to produce a certain amount of carbon emissions and that can be traded if the full allowance is not used.
Q. Water: where did it come from?
A. The oxygen came from stars that lived and died before our Sun was even born. When those stars puffed out their final breaths of oxygen, carbon and other “metals”, they seeded new nebulae with the raw material for new worlds. We owe our very existence to the dead stars that came before.When our Sun dies, it’ll give up some of its heavier elements to the next generation of stars. So, mix hydrogen together with this donated oxygen, and you’ll get H20. It doesn’t take any special process or encouragement, when those two elements come together, water is the result.
Q. Where is “usable water”?
A.Even though most of the Earth's surface is water, only 1% of it is fresh usable water. Ninety-seven percent of the Earth's water is saltwater, which contains too many minerals for humans to use untreated. Two percent of our water is "locked up" in ice caps and glaciers, leaving only one percent as usable fresh water.
