Needed: Local Advocacy and Action on Climate Change

Sat ,08/07/2017

There were three great letters in the Wichita Eagle recently. The first describes how renewable energy is growing and may soon meet much of our energy needs; the second describes the advantage of using a Carbon Fee and Dividend system to reduce pollution; and the third describes how cities may use electric vehicles in their transit system to cut air pollution.  The letters are printed below with the authors’ permission.

Green energy (Wichita Eagle, June 28, 2017)

I read with interest the column by Ed Cross about energy and the need for American energy independence. I’m afraid I need some help defining his  “extreme environmental activist.” Is it a person who favors any type of energy besides fossil fuels? Is it a person who wishes to return the United States to using coal entirely to produce our electric power?

I would guess that Cross did not enjoy the latest statistics from the alternative energy sector: In the first three months of 2017 the entire United States derived 10 percent of its electric power from solar and wind energy.

If you look at the mathematical curve describing the growth of solar and wind power in the past 10 years, it is exponential. Naysayers regarding green energy have said for years it is a mere Boy Scout experiment, it will never produce significant power.

The power that was produced last year by green energy sources in the United States exceeds the total electric power consumed by the entire nation in the year 1950. The United States at that time was a highly developed industrial nation that was producing vast quantities of steel, and other high-value, energy-intensive products.

There is no question that if we stay on course with where we have begun, green energy sources will clearly surpass fossil fuels for every purpose within the next few years.

If Cross is so interested in American energy independence I am puzzled as to how he can be opposed to American green energy. By definition green energy must be produced here in our country and nowhere else.

Coming together on an energy policy (Wichita Eagle, June 30, 2017)

The op-ed (June 25) by Edward Cross calls for energy policy discussions without the divisiveness of the past. I agree.

As a volunteer with non-partisan Citizens’ Climate Lobby, we bring Republicans and Democrats together to talk about energy and climate solutions. We have identified a market-based solution called Carbon Fee and Dividend that grows the economy, levels the field for foreign trade, and puts more money in the pockets of consumers. Four of the six largest oil companies signaled their support for this type of plan just last week.

I appreciated Mr. Cross reporting an improvement we can take comfort in, that from 2005 to 2016, 60 percent of carbon reductions in electric power production were due to fuel switching from coal to natural gas. Kansas wind helped reduce CO2 as well. Switching from coal to gas cuts emissions about 50 percent, but wind or solar cuts it to zero.

Americans want a common-sense energy policy like Carbon Fee and Dividend that sparks innovation that appeals to liberals and conservatives. No yelling needed, just respectful discussions.

City’s emissions ( Wichita Eagle, July 2, 2017)

It is hard to believe that Wichita has a smog problem, but it does. Wichita’s Department of Public Works should be commended for its work in reducing ozone emissions, but more needs done.

Wichita could further reduce emissions by buying electric vehicles when its buses and vans need replacing. Park City, Utah, replaced its diesel buses and found that, though they cost more to purchase, they saved money over time. They reported an equivalent 21 mpg compared with 4 mpg for a standard diesel bus.

Large power plants produce about twice as much work for a given amount of fuel as an internal combustion engine. That means that using electric vehicles cuts fuel use and emissions by about 50 percent. By using electric vehicles, Wichita could save money on fuel and maintenance, cut ozone emissions within the city, and reduce carbon emissions overall by about 75 percent. That sounds like a good investment.

Note : This letter was shortened for printing so a bit more explanation is needed. Because of the efficiencies involved, using electrical vehicles cuts the emissions by about 50%, even if charged from a coal-fired power plant. Since Wichita uses Westar Energy which gets 51% of its electricity from non carbon sources, the emissions are cut in half again, giving an overall reduction of 75%.  And, the emissions are at the power plant rather than within Wichita.

The authors are members of the Citizens’ Climate Education and the  Citizens’ Climate Lobby  groups in Wichita. They are both strong advocates for a carbon fee and dividend system to ensure clean air, pure water, and a healthy future for our children.
