Energy sources and energy use is fundamental to many of the articles, safety moments and posts at this site.

Solar and Wind

 

Solar and wind energy lie at the heart of all Net Zero programs. Other sources of energy can play important roles, but none of them are as crucial as solar and wind. 

In spite of their importance, solar and wind have four major drawbacks.

  1. They are intermittent;

  2. They are not dispatchable;

  3. They require a lot of space; and

  4. They do not provide transportation fuels.

An Energy Evaluation System

At the heart of any Net Zero program lies the decision as to which alternative energy sources to adopt. We cannot continue to rely on hydrocarbon fuels — coal, natural gas and crude oil — because they generate greenhouse gases, and because they are being irreversibly depleted.
