Perspective

"The transition from fossil fuels to renewable resources is a long and expensive but an absolutely vital process. We need a long term (30 to 50 years), high-priority program using a substantial part of the GNP and covering the entire scope – from fundamental research to commercial installation strategy – to gradually replace the fossil fuels we use for power generation, transportation and industrial thermal energy."

RESEARCH - BIOFUELS

Biomass measures up to petroleum

March 9, 2009
We know that biofuels, to a greater or lesser degree, are environmentally better than petroleum-based fuels. It turns out that many are also comparable to petroleum fuels in cost and production efficiency. [more]

RESEARCH - SOLAR

Light splitting boosts solar cells

March 9, 2009
Split sunlight with a color-separating mirror and you get more electricity out of the same light if you aim it at two different types of solar cells. [more]

RESEARCH - HYDROGEN

Coated nano mesh gets more out of light

March 9, 2009
Coat a net-like nanostructure made of one titanium semiconductor with a second titanium semiconductor and you can boost the amount of light the structure converts to electricity, and possibly the amount of hydrogen it extracts from water. [more]

FUNDING & POLICY

Chu to Congress: more research funding

March 6, 2009
Research was a major theme of energy secretary Steven Chu's statement to the Senate Committee on Energy and Natural Resources yesterday. [more]

RESEARCH - BATTERIES & CAPACITORS

Recycled newspapers store electricity

March 2, 2009
Give used newspapers a bath in the right chemicals and you get a green twofer: cheap ultracapacitor electrodes for storing electricity and a new use for recycled newspaper. [more]

RESEARCH - BIOFUELS

Hauling ethanol nixes benefits

March 2, 2009
Ethanol's slogan should be keep it local, or at least regional, if the biofuel is to serve as a truly green alternative to gasoline. [more]

RESEARCH - SOLAR

Fool's gold promises cheaper solar

February 23, 2009
Come up with a way to make solar cells from iron pyrite -- fool's gold -- and you could have a cheap, abundant energy source. [more]

RESEARCH - BIOFUELS

Chemical simplifies cellulosic biofuel production

February 23, 2009
Cook up the right solvent and you can turn wood and agriculture scrap directly into a biofuel precursor without first having to convert it to sugar. [more]

RESEARCH - BATTERIES & CAPACITORS

Nested nanotubes promise better battery electrodes

February 10, 2009
Grow carbon nanotubes inside manganese dioxide nanotubes and you've got high-capacity, potentially inexpensive electrodes for lithium-ion batteries. [more]
