ABSTRACT: Biofuels are by now a well-established component of the liquid fuels market and will continue to grow in importance for both economic and environmental reasons. To date, all commercial approaches to biofuels involve photosynthetic capture of solar radiation and conversion to reduced carbon; however, the low efficiency inherent to photosynthetic systems presents significant challenges to scaling.

ABSTRACT: Public policies at both the state and federal levels in the United States and a variety of technological and economic changes are poised to significantly alter both the demand for and supply of electricity in the country over the next several decades.

ABSTRACT: After a century of unprecedented growth in science, technology, and the economy, we now face tremendous challenges to our ability to fuel the future: a fluctuating oil price, a changing climate, and continued dependence on unreliable energy sources. These problems are increasingly personal, and the demand for solutions becomes increasingly urgent. There are many changes that we must make to address these challenges, but the ultimate solution(s) will only come from fundamental innovations in science and technology.

ABSTRACT: My parents nurtured my awareness of the big problems facing our world and throughout my life have supported me in my desire to find solutions, even though this meant I was not following any kind of conventional career path. I have also been fortunate to have friends, colleagues, and my own wife and family, who have encouraged me in hard times, and never doubted that devoting my life to working on solutions to climate change was what I should be doing.

ABSTRACT: Energy storage has mainly focused on electrochemical systems. However, more than 90% of the world's primary energy generation is consumed or wasted thermally. Thermal energy storage has a broad and critical role to play in making energy use more sustainable for heating and cooling, solar energy harvesting, and other applications. Thermal storage technologies are still based on solutions developed decades ago, such as molten salt, ice, and paraffin phase-change systems, whose performance and cost do not merit widerscale adoption. Progress in materials science, chemistry, and engineering may lead to dramatic breakthroughs in thermal energy storage that could improve the efficiency with which we produce, distribute, and consume energy.
