The energy crisis in California is a wake-up call: we have a serious energy supply problem in this country. And it’s only going to get worse: according to US government figures, overall domestic energy consumption is expected to increase by more than 30% in the next 20 years.
Demand for oil will increase by one-third, yet we now produce 39% less oil than we did in 1970. Consumption of natural gas is expected to increase by 62% over the next two decades. More than 61% of US residences (58 million homes and apartments) are heated with natural gas.
But 40% of our domestic gas resources are now off limits or so restricted that development is virtually impossible. Electricity demand will increase by 45% over that same period, owing at least in part to the growth of power-hungry information technology. In the multifamily sector, 42% of all units built in 1999 featured natural gas heat; 56% of those new units featured electric heat. Coal currently provides more than 50% of electricity generation.
