Relevant Terms

Compact Florescent Lamp (CFL) - A small fluorescent light bulb that uses 75% less energy than a traditional incandescent bulb and can be screwed into a regular light socket.

Global Warming - an increase in the average temperature of the lower atmosphere resulting in climate change. While it can have many different causes, global warming is most commonly associated with human activities that result in the emission of greenhouse gases.

Greenhouse gases - a gas, such as carbon dioxide, methane and ozone, that traps the sun's heat and contributes to global warming. Burning fossil fuels emits greenhouse gases.

Organic - Grown without the use of pesticides, synthetic fertilizers, sewage sludge, genetically modified organisms, or ionizing radiation. Animals that produce meat, poultry, eggs, and dairy products do not take antibiotics or growth hormones.

Solar Panel - Array of photvoltaic cells that make use of renewable energy from the sun, and are a clean and environmentally sound means of collecting solar energy.

Solar photovoltaic (PV) energy - direct conversion of sunlight to electricity, producing no emissions. PV panels contain semiconductors such as silicon that collect and absorb solar energy, producing direct current (DC) electricity. An inverter device is used to convert the DC current into alternating current (AC) electricity.

Sustainability - Meeting the needs of the present without compromising the ability of future generations to meet their own needs.
