watt
Unit of power, or rate at which electrical work is done. See kilowatt.
Subject:
Superinsulated house
House that is heavily insulated and extremely airtight. Typically, active or passive solar collectors are used to heat water, and an air-to-air heat exchanger is used to prevent buildup of excessive moisture and indoor air pollutants.
Subject:
solar collector
Device for collecting radiant energy from the sun and converting it into heat. See active solar heating system, passive solar heating system.
Subject:
solar cell
See photovoltaic cell.
Subject:
Radioactive waste
Waste products of nuclear power plants, research, medicine, weapon production, or other processes involving nuclear reactions. See radioactivity.
Subject:
photovoltaic cell (solar cell)
Device which converts radiant (solar) energy directly into electrical energy.
Subject:
passive solar heating system
System that captures sunlight directly within a structure and converts it into low temperature heat for space heating or for heating water for domestic use without the use of mechanical devices. Compare active solar heating system.
Subject:
net energy
Total amount of useful energy available from an energy resource or energy system over its lifetime, minus the amount of energy (1) used (the first law of thermodynamics), (2) automatically wasted (the second law of thermodynamics), and (3) unnecessarily wasted in finding, processing, concentrating, and transporting it to users.
Subject:
Micropower systems
Systems of small-scale decentralized units that generate 1-10,000 kilowatts of electricity. Examples include (1) microturbines, (2) fuel cells, and (3) household solar panels and solar roofs.
