Before too long we will all be driving cars that are powered by non-polluting energy. We must also ensure that these energy types are also not produced from polluting sources and are sustainable.
In the end there needs to be a breakthrough in battery technology and energy storage so that fuels like electricity produced by solar and wind can be stored.
For now, oil prices are a bellweather of the economy. Oil prices have doubled in the last few months and fuel at the pumps has gone up in price. I guess this suggests more optimism for the year ahead.
