An American way to a zero-carbon future



Published:

If we’re concerned about global warming, endless wars for oil, nuclear proliferation and our economic future, then we need to face four very convenient truths. Combining four very American enthusiasms — the automobile, electricity, free renewable fuel and market opportunities — makes a zero-carbon future ours for the taking. That’s right. In this zero-carbon future we can drive with no gas and no pollution, turn on our computers to connect us to a smart global grid and get checks in the mail every month for our troubles. The technologies are at hand or need just the slightest push. New plug-in electric cars using lithium-ion batteries will be charged at night from a renewable grid and help provide peak daytime power while we’re at work. This is doable. Just a small percentage of our millions of cars can give us much of the energy needed to balance and stabilize a renewable energy grid system. Copious wind resources on farm and ranch land from the Dakotas to Texas will be combined with solar electric concentrators and photovoltaic panels from the Southwest and local photovoltaic arrays covering our roofs and parking lots. DC power lines, underground if necessary, will facilitate moving the power to where it’s needed. The system will be integrated and coordinated through a smart electric grid using real-time price control to optimize energy use and energy generation. We’ll buy power when it’s cheap, and sell it back into the grid when it’s expensive. By using renewable energy hedges, like the one negotiated between Southern New Hampshire University and PPM Energy, every energy consumer and car and photovoltaic panel owner will have a profitable stake in our common renewable energy future. We can use our energy purchases and investments in plug-in vehicles and photovoltaics to fix our net annual energy expenses for a generation, and receive monthly income for buying our grid-tied cars and home photovoltaic systems. There’s more. Combined heat and power that turns every heating system into a micro-generator and district heating from existing urban power plants should play a part. Compressed air, capacitors and flywheels can help balance the renewable grid. We need to adopt high-efficiency standards and zero-pollution industrial ecological practices using “waste” from one process as input for another. We can use duckweed and water hyacinths fed by our sewage plants and agricultural runoff to produce enormous amounts of biomass for biofuels. We can make the whole thing work rather painlessly by phasing out income taxes, abolishing the IRS and phasing in ecological consumption taxes on all goods and services. If something pollutes more, it will cost more. If something pollutes less, it will cost less. The market price, not just regulation will tell us what to do. Wake up America. Let’s use our cars, electricity, free renewable fuel and the market to build a zero-carbon, sustainable and peaceful future.
