Energy Options for Today

There have been a couple recent developments in the energy field that can help you simultaneously reduce your energy bill and reduce your impact on the environment. Specifically, with increases in the efficiency of and decreases in the price of solar electric (photovoltaic) panels and solar water heating systems, and with innovative financing options, many Vermonters can now produce their own electricity or hot water at costs at or below what they are currently paying. In fact, it is often possible to install a photovoltaic system for zero money down and to pay the same amount for electricity as your current electricity bill for 15 years – i.e., while all your neighbors’ electricity bills are increasing year to year, you can pay the same amount you’re currently paying. And after 15 years, you will own the system and will have virtually free electricity for another 15 years or so!

Another major development has been the commercialization of cold weather heat pumps that can “harvest” heat from the air outside your house to heat it. Cold weather heat pumps can cost-effectively provide around 80% of your heating needs, typically providing useful heat down to around 0°F. Similarly, heat pump water heaters can provide hot water for your home at a cost less than oil, propane, or electricity.

If you would like to learn more about these energy- and money-saving technologies, please attend the free public Energy Options for Today workshop, sponsored by the Underhill Energy Committee. The session will be on Tuesday, October 28, from 7:00 – 9:00 PM, upstairs in the Underhill Town Hall in Underhill Center. The evening will begin with brief presentations by several local installers of solar and heat pump systems describing their products and their expertise. Next, we’ll open the floor to general questions. Following that, attendees will have an opportunity to visit each of the installers at tables set up around the hall.

Soooo Smooth

In the New York Times's Dot Earth blog, Andrew Revkin writes 13 March 2013 about a new study, Examining the Feasibility of Converting New York State’s All-Purpose Energy Infrastructure to One Using Wind, Water, and Sunlight.


A graph from a study concluding that New York State can shift from fossil fuels to wind, solar and water power by 2050.


This graphic comes from the report. It reminds me of the Socolow and Pacala wedges. What's wrong with the wedges and this picture? It's soooo smooth, which gives the viewer the notion that all that is required is a gentle transition in policy and technology. What's actually required to make the transition is to make every single decision to be the most deliberate and dramatically effective. That's because -- as Revkin points out in arguing against rapid action -- in New York City "80 percent of the buildings that will exist in 2050 are already here today." A similar issue exists for of cars, and their infrastructure of roads, water, sewer, energy. etc.

Revkin strikes a skeptical stance and challenges the authors in an email exchange.

A couple of items standout in a reply:

1) Instead of upgrading, maintaining, and replacing deteriorating existing infrastructure, invest in new infrastructure. If we don’t appreciably accelerate retirement, there is no “extra” (early-retirement) cost to consider.
2) Retrofit and rebuild for maximum efficiency and minimum environmental impact. The correct basis for evaluating this economically is a full social lifetime cost-benefit analysis with a near-zero discount rate. On this basis, I believe that most improvements will be economical.

It is a goal-oriented way of thinking, "What will it need to be like?", not back-looking, "Where can we go from here?"

Ditching the discount rate is necessary. It inhibits good decision-making.
