Electric cars, ships, and planes, and manufacturing plants powered completely by the wind and the sun are probably the most urgently needed commodity.
The tragedy is that given the exponential nature of the global warming problem, if we don't see a major shift to such commodities in the next 25-50 years, there will be nothing that humans can do to stop the increased warming that will occur after that, even if we never burn fossil fuels afterwards, because several large positive feedback mechanisms not included in current climate models will come to dominate the global climate system.
These positive feedbacks include Arctic amplification due to dramatic increase in albedo of the Arctic, release of huge stores of carbon trapped in permafrost, release of huge stores of carbon trapped in methane clathrates, and release of carbon from peat bogs and rainforests as soils dessicate and decomposition dominates carbon fixation from photosynthesis. These sources are so large that they dwarf what humans could do to lower carbon dioxide levels. Of course, the effects on total carbon dioxide will be additive in any event.
Few notice, but the trend in oceanic environments are not good, as the sea warm more and more phytoplankton and zooplankton move northward to physiologically optimal zones leaving behind the equivalent of photosynthetic deserts. Tropical marine ecosystems are now collapsing everywhere on the planet as the Earth shifts toward a new oceanic/atmospheric thermal equilibrium.
