Document Summary
Renewable resources: natural sources, sustainable replenished, water, solar, wind, biomass, geothermal. Reducing our consumption: try to reduce and make our energy use more efficient, standby energy consumption is how we use most of our energy, home office, tvs, etc. Include extra insulation and coated windows: natural light, use 90% less energy, nc wildlife resources commission, talley and hunt library. Cogeneration produces electricity and heat: cogeneration-simultaneous production of both electricity a team, or hot water in the same plant. Interest is being renewed: district heating systems are being rejuvenated, plants that burn municipal waste are being studied, apartment-building-sized power generating units are being built that use methane, diesel or coal. High temperature solar energy: concentrated solar power (csp, technologies that concentrate solar energy to generate electricity, mirrors tracks the sun"s movement, parabolic mirrors: curved reflective surfaces that collect light and focus it into a concentrated point. Pros of solar energy: use no fuels, are quiet, safe, contain.
