in a house what houshold objects are good or bad because of the environment and y?

Answer 1

Just an addition to Mr. P's renewables is solar thermal, ie, setting up a whole heap of mirrors and reflecting the sun's heat to a central location where there is a steam turbine. The water heats up, goes through the turbine and creates electricity. Something the size of a sports grandstand could power a largish town. They are building one in Spain right now that's huge and will be enough to power half of Seville, a city with a population of around 1 million. It's a very effective and promising renewable technology that most people don't think of and know about.

Answer 2

Ooooh - I can feel an essay coming on - is that what you've been given?

Renewable - Hydroelectric, wind, tidal, solar, geothermal, biomass.

Reusable........ Probably wasted heat from other processes (in industry).

Bad things In the home - probably items that waste electricity or heat, such as entertainment systems, ineficient lighting and heating and lack of insulation.

Good things in the home would be solar water panels, efficient building design, condencing heating systems and economical appliances.
