Survey Shows Costs of Energy Conservation Going Down

Energy Central trae la siguiente noticia:

This week, the conservation side of that equation received a jolt of good news, with a council survey revealing that conservation costs have dropped dramatically.

In 1991, the average price tag for conserving a megawatt of electricity was $3.9 million. Today, that same megawatt can be had for $1.6 million. (A megawatt is enough power to light 10,000 100- watt light bulbs continuously for one year.)
Since conservation has zero marginal cost it can be favorably compared to investments in hydro power, which in general are much more expensive and have environmental impact.
