Generating Electricity from Fossil Fuels

The simplest, quickest and cheapest full time electric power system is one built around a fuel driven electric generator. Such a system is not "renewable" energy and there are a number of disadvantages of generator bases systems, but there are a number of significant advantages as well, even if renewable energy sources are planned for.

An initial system based on a generator can be expanded to include renewable energy generation with the generator retained as (1) a backup and (2) a high capacity bulk charger for periodic "battery equalization (see the power system design page and the battery page). A system that balances the use of solar and fossil fuel, along with wind or water where appropriate, will cost less and deliver more capability than either solar or fossil fuel systems used alone. What often happens however is that a decision to use renewable energy exclusively is based on a matter "principle" rather than sound engineering analysis.

Of the common fossil fuels, diesel is by far the best choice for power generation owing to it's safety, availability, energy content, and motor design. Diesel engines, especially those designed for industrial duty, are highly reliable, cost little to maintain, and will suffer considerable abuse -- intentional or otherwise -- without damage.

Before you make any decision about diesel generators, let alone actually purchasing one, our book How to Save 50% or More on the Purchase of a Diesel Generator is a must read. You will learn how to save literally thousands of dollars on a generator purchase -- enough to buy a whole bunch of solar cells!
