  • The Climate Crisis and the Transition to a Renewable Economy

    What I am betting on is the growing sense of awareness and understanding of environmental issues among the people of the world. It could be that my personal perspective is a little warped. I’ve seen the environmental issue move from the outer fringes to the center of our political agenda.

  • Fossil Fuel Companies Need to Become Renewable Energy Companies

    No one should underestimate the scale of the challenge that confronts humanity. It will require new technologies and changes in infrastructure, organizational capacity, economic incentives and public policy.
