Many conscientious environmentalists are repelled by the word “abundance,” automatically associating it with irresponsible consumerism and plundering of Earth’s resources. In the context of grassroots frustration, insensitive enthusing about the potential for energy abundance usually elicits an annoyed retort. “We have to conserve.” The authors believe the human family also has to _choose_. The people we speak with at the recycling depot or organic juice bar are for the most part not looking at the _difference_ between harmony-with-nature technologies and exploitative practices such as mountaintop coal mining. “Destructive” was yesterday’s technology of choice. As a result, the words “science and technology” are repugnant to many of the people who passionately care about health, peace, justice and the biosphere. Usually these acquaintances haven’t heard about the variety of constructive yet powerful clean energy technologies that have the potential to gradually replace oil and nuclear industries if allowed. Wastewater-into-energy technologies could clean up waterways and other variations solve the problem of polluting feedlots and landfills.
