Most Texas homes weren't built as if energy mattered. Despite 100-degree summer days, our roofs are still covered in heat-absorbing black-tar shingles. Cheap insulation in the attic, leaky doors, and single-paned windows mean when the air conditioner runs, it runs loads of cooled air right out the house. San Antonio's CPS Energy plans to spend $850 million to eliminate 771 megawatts of wasteful energy consumption through weatherization programs and rebates to help residential and commercial customers replace lights and appliances, and hoist solar panels onto their roofs by 2020. To do that will cost roughly $1,100 per saved kilowatt, according to the utility. However, 80 miles to the northeast, municipally owned Austin Energy has already cut 800 megawatts through energy efficiency over the last 20 years at a cost of roughly $350 per kilowatt, said Scott Jarman, consulting engineer with Austin Energy's efficiency program. But after 20 years of efficiency work, the savings are increasingly hard to find, and accordingly, more costly.
