I can explain the technical and economic tradeoffs of making electricity from natural gas, coal, nuclear, wind, solar, and biomass energy sources. I'm familiar with air pollution control technologies. I have a good understanding of the science on global warming and can explain how the various fuels and energy conversion technologies contribute to that process. I can tell you why we have to build more new nuclear, wind, and solar power plants, but will still have to keep using coal for a long time to make elctricity. I understand energy conversion efficiency. However ... I'm not an electrician, so probably cannot help with any questions on motors or wiring.
Forty years as a registered professional mechanical engineer.
Graduate of Purdue University, School of Mechanical Engineering.
EPA, DOE, State Department, USAID, World Bank, Bechtel Power Corporation, U.S. Generating Company, numerous electric utility and independent power companies.
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 and electric power generation with as many 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% or more and energy prices will have at least doubled in real terms, 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.

John - a) Let's say the the electrical generator is a very efficient combined-cycle unit with a heat rate of 7000 Btu/kWh. It would consume fuel at the rate of 7 million btu/MWh. So a 1 MW unit would
David - Sorry for the tardy response. I've been on a short vacation. And, sorry to say I'm no expert in gasifier design. But let's explore your question anyway. It's clear that if one has the total
Raj - A supercritical steam power plant uses a boiler that makes steam at a pressure above the "critical pressure" of water. One would choose a supercritical high pressure and high temperature design
Guarang - a) Let's say the the electrical generator is a very efficient combined-cycle unit with a heat rate of 7000 Btu/kWh. It would consume fuel at the rate of 7 million btu/MWh. So a 1 MW unit would
Jay - Let's say the the generator is a very efficient combined-cycle unit with a heat rate of 7000 Btu/kWh. It would consume fuel at the rate of 7 mmbtu/MWh. So a 1 MW unit would need 7 mmBtu per hour
