Craig Shields
California, USA
Editor of 2GreenEnergy, a website purposed to provide information, consulting, and investment products and services to companies in sustainability, renewable energy, and electric transportation.
Interests: My interests include sustainability in general, renewable energy technologies (especially solar thermal using molten salt as an energy exchange and storage medium), advances in energy efficiency, the economic opportunities available to capital investors and other businesses in moving away from fossil fuels and wasteful practices, ethics and integrity in politics (de-legitimizing bribery), preventing catastrophic climate disruption, exposing the danger and unfeasibility of nuclear power plants, helping to relegate petroleum to the pages of history as a predominant source of energy in human society.

Most of our liquid fuels are used for the ground transportation of goods and people - applications for which electric transport is ideally suited and far more efficient. I firmly believe, after careful consideration, that electric vehicles - trains, trucks and cars - are the direction we should be going, and we should be using solar thermal with molten salt storage distributed across the Sunbelt and feeding power to the whole nation via high voltage direct current transmission. Here's a little more discussion on those options: IMO, investing money, time, resources and expertise in the conversion of sunlight to liquid fuel to be burned in inefficient vehicles is a stepping stone set in quicksand that we neither need nor can afford.

HarveyD makes an excellent point. By a recent estimate we the humble taxpayers pay $550 billion a year in a steady and predictable stream of subsidies and tax breaks to dirty fuels while renewables have to woo investors backed by a spotty record of fits and starts in government funding and support that look ant-like by comparison to the dirty fuel elephant. SJC likewise sagely observes that there's an employment boom to be found in the support of renewable energy technologies. Here's a little more discussion on that: Government funds gave us the post office, the national highway system, the microchip, and the internet. The chief mandates of any good government are to provide for the common defense and promote the general welfare. If we continue to fail to use our collective strength - a democratic republic and its power to tax and spend - to wean ourselves off of oil, we'll be defenseless against energy blackmail and quickly bereft of any control over our well-being.

Any strides we can make toward a less polluting, more efficient personal vehicle are positives in my view, and all-electric vehicles are a personal favorite of mine. There are those who say that an electric car is only as green as the power plant that charges it, and therefore the car is simply moving the carbon from the tailpipe to the smokestack, but in fact when the batteries are charged during off-peak hours (as they likely usually would be) they're just feeding off the baseload and wouldn't tax the grid unduly at all. Electric cars are also more energy efficient in their use of the power they take, while most of the energy used in petroleum fuel vehicles is wasted in the form of heat and mechanical inefficiencies (not to mention the energy cost of refining and transporting the fuel). Bravo, Sion! Craig Shields,
