I'm a professional mechanical engineer. I can explain the economic tradeoffs of making electricity from natural gas, coal, nuclear, solar, and biomass energy sources. I have a pretty good understanding of the science on global warming and can explain how these energy conversion technologies affect that process. I can tell you why we have to build more nuclear plants, keep using coal, and cut way back on using natural gas to make elctricity. I can de-mystify the concepts of efficiency and energy conservation. But, I'm not an electrician so I don't do wiring! :-)

Energy conversion makes the world go round! Everyone is interested in energy matters, but not many are asking the kind of questions needed to make informed choices about our energy future and how it affects the environment of our planet.
I want to share my 40 years experience and knowledge of energy conversion with as many young people and parents of young people as possible.
The electricity consumed by an average American household in a year requires burning about 5,000 pounds of coal to produce that electricity.
By the time today's 1st grader graduates from an engineering college, electricity use will have increased by 50%, oil and gas will not be allowed as fuels for electricity, energy prices will have at least doubled, and the world may need to use more than twice as much coal and nuclear energy. The times are changing, and way too little public education is being provided on all of this.

Hi John - When electricity leaves a power plant and is transmitted hundreds of miles over high voltage lines, finally being reduced in voltage and distributed to our homes, industry, and businesses, the
Scott - It all boils down to (no puns!) ... All right, it all depends on temperature. In the ideal Carnot heat engine of classical thermodynamics, the greater the difference between the average temperature
Suketu - Sounds like you might just have to live in the home for a month and keep track of the meter readings to see if they make sense. If they do not make sense, then you'll have the data you need in
Suketu - We live in a 2500 sq ft home. We have a gas water heater and gas clothes dryer. We both work, so are not at home half the day on weekdays. We use about 200 kWh per month during the spring, fall
The main attraction of nuclear power plants is that they produce no carbon dioxide (CO2) greenhouse gas, thus they do not add to global warming in the way that coal-fired plant do. There is a concern that
