Power Generation Efficiency - an overview | ScienceDirect

The first electrical power plants were very inefficient, with the thermal efficiency steadily increasing with improved equipment design. Data summarized by Haywood 1 and shown in Figure 7-4 illustrate this improvement in electrical powergeneration efficiency over the past century. In 2002, the most efficient power plants converted 53% of the energy in natural gas to electricity.

Furnaces and Boilers | Department of Energy

Energy efficiency upgrades and a new high-efficiency heating system can often cut your fuel bills and your furnace's pollution output in half. Upgrading your furnace or boiler from 56% to 90% efficiency in an average cold-climate house will save 1.5 tons of carbon dioxide emissions each year if you heat with gas, or 2.5 tons if you heat with oil.
