==Energy efficiency==
There is unanimous agreement from all points of the spectrum that the cheapest, easiest and quickest way to save on energy costs and reduce imported oil is to reduce waste and be more efficient on the consumer side--especially in insulating residences and using more efficient appliances and automobiles. Many local electricity and gas companies have rebate programs; the federal government offers $1500 tax rebates to ordinary Americans, and many states have somilar programs in 2010.<ref> See [http://www.energystar.gov/index.cfm?c=tax_credits.tx_index "Federal Tax Credits for Consumer Energy Efficiency" 2010]; for state rebates see [http://www.dsireusa.org/ The Database of State Incentives for Renewable Energy (DSIRE)]</ref>
