COLD ENVIRONMENTS All Definitions: * Quaternary Period: the latest period in geological time spanning the last 2 million years. It is sub-divided into the Pleistocene epoch (the most recent ice age) and Holocene epoch (the post-glacial period of last 10000 years). * Glacial: a period of time when masses of ice develop and advance into lower altitudes due to a sustained decline in temperature. Extensive continental ice sheets form during such periods. * Interglacial: a period of time

Title: SOLAR ENERGY: “SUNLIGHT into USEFUL ELECTRICITY” >Introduction< In today's climate of growing energy needs and increasing environmental concern, alternatives to the use of non-renewable and polluting fossil fuels have to be investigated. One such alternative is solar energy. Solar energy is quite simply the energy produced directly by the sun and collected elsewhere, normally the Earth. The sun creates its energy through a thermonuclear process that converts about 650,000,000 tons

GLOBAL WARMING Introduction Global warming begins when sunlight reaches Earth. The clouds, atmospheric particles, reflective ground surfaces and ocean surface then reflected about 30 percent of it back into space, while the remaining is absorbed by oceans, lands and air. This in turn heats the planet’s surface and atmosphere, making life possible. As Earth warmed up, this solar energy is radiated by thermal radiation or infrared heat, traveling directly out to space, thus cooling the Earth. However

Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, air and water heating/cooling, motor fuels, and rural energy services. Based on REN21's 2014 report, renewables contributed 19 percent to our global energy consumption and 22 percent to our electricity generation in
