Allow the energy you buy to perform its best.

The price of energy is going up.

I have analyzed the energy bills (from Pepco and Washington Gas) from my office in Takoma Park Maryland and you can see how the cost of electricity and natural gas have changed with time on this page. The electricity costs have been converted to United States Dollars per million BTUs.

You can see that electricity is a lot more expensive than Natural Gas and its cost is rising more rapidly and steadily. In September 2009, electricity was 4.4 times the cost of gas when converted to the same units, up from 2.8 times in 2003. The jogs up and down for electricity are due to the difference in summer and winter rates.

Natural gas cost is a little more steady than the price of electricity, rises and falls, In May 2008 natural gas peaked at its highest price since the time of Hurricane Katrina in 2005, but recently has been very steady and fallen to the price it was at in 2003.

Forms of Energy

In our area, most energy is delivered to homes in the form of either electricity or natural gas.

Electricity is sold by the kilowatt hour (kWh) - An old style 100 watt incandescent bulb burning for 10 hours is a kilowatt hour.

Natural Gas is sold by the therm. A therm is one hundred thousand British Thermal Units (BTUs). One BTU is about the heating energy of one wooden match.

A convenient unit is millions of BTU (MBTU) for both electricity and gas to allow comparisons. There are 3413 BTU in one kWh of electricity.
