I am a philosopher as well as an activist.
As the former I ask: Why do we continue to render uninhabitable much of our planet? What forms of ignorance and neglect are entailed?
As an activist, I support the efforts of The Genii - The Global Energy Network Initiative. Their monthly newsletter is available at this site:
It is a project inspired by Buckminster Fuller's vision of the land masses (on the planet on which we all reside) interconnected with shared power grids. This reinforces our interdependence upon one another and thus makes war between regions less likely.
I spread the word that it is a fact that a very small portion of the Earth's deserts could supply all the power that Western Civilization needs via solar energy installations.
This has to be supplemented with good sound transmission lines and cables to transport the virtually-free energy to places which are population centers. Hence I support the recent agreement between the nations in the North-African Alliance and those in Europe to share power grids. I welcome such cooperation. This is good news!
At the same time I believe in decentralized power sources, and am working for the rehabbing of business buildings to conserve energy; as well as for the placement of green, clean power-supply mini-windmills on each roof, and solar-energy panels in each backyard. I put pressure on local governments and utilities to supply money for this cause, to allocate resources to this end. :You could do the same.
