For millennium no one knew how the sun worked. Then in 1905 Albert Einstein discovered that energy and mass were interchangeable with his famous formula, energy equals mass times the speed of light squared (E=MC2). In other words, a little mass can give a whole lot of energy. In the 1930’s it was discovered that if you bombard Uranium 235 with neutrons you create a chain reaction which can unleash that energy. This led to the development of the atomic bomb in WWII.

In 1955 the navy developed the first nuclear powered submarine. That technology was developed to generate electricity that is now operating approximately 430 nuclear power plants in the world, around 100 in the U.S. generating around 20% of our electricity. However, starting in the 60’s and 70’s, concern developed regarding the safety of these nuclear plants and the long term disposal of highly radioactive nuclear waste. The nuclear accidents at 3 Mile Island, Chernobyl and Fukushima and the failure establish a long term nuclear waste depository at Yucca Mountain, Nevada has rightfully fed into these legitimate concerns.

However alarms over the environmental effects of global warming resulting from massive CO2 emissions have led some environmentalist to reevaluate the relative dangers of nuclear power. Nuclear power plants emit no CO2 or any air pollution. Estimates vary but air pollution from burning fossil fuels for electricity kills around 1.5 million people a year worldwide from stokes, heart disease, COPD, cancers, asthma and other diseases (WHO). Coal is a particularly destructive source of energy not just from air pollution but from mining and disposal of millions of tons of toxic coal ash.

The Chernobyl accident accounts for all documented deaths from all nuclear accidents at around 78. Long term increased cancers from low level radiation spread from Chernobyl and Fukushima (none from 3 Mile Island) are difficult to measure and estimates vary widely from zero to thousands spread over decades but nowhere near that from burning fossil fuels.

All nuclear power plants are not the same. The Chernobyl reactor was a terrible, dangerous design that no longer exists and the Fukushima plant had major serious design flaws that could not handle the tsunami that struck it. Modern existing designs are far safer and more efficient and there are many advanced experimental designs that would eclipse even those. Fusion nuclear reactors promise unlimited clean energy from seawater with no nuclear waste and no possibility of a nuclear accident.

Long term storage of nuclear waste does not yet exist but existing intermediate term storage in concrete and steel silos could provide indefinite safe storage. Radioactive decay continuously reduces the dangers that these wastes pose. Existing and advanced nuclear reactor designs could use nuclear waste as fuel to greatly reduce or eliminate radioactive waste.

In conclusion: Nuclear energy has its risks that need to be evaluated seriously but its 60 year record is far less environmentally dangerous and destructive than burning fossil fuels. Existing nuclear power plants should be kept in operation and modernized whenever possible. New nuclear power plants may not be financially viable, at least in the short run, because of the current abundance of cheap natural gas unless there is a carbon tax or carbon credits. Later in this century fusion power may provide mankind with unlimited clean and safe energy but until then energy conservation, improved efficiency and renewable energies like solar are always the best way to go.

A brand new Fracking Impact Study (August 2015) should be required reading for all of the residents who live in and around the Delaware River in the shadow of the shale gas boom. The report was commissioned and published by the Delaware RiverKeeper Network, an advocacy group aimed at preserving the health of the Delaware River. The Fracking Impact Study quantifies the potential harm to the environment and residents along the Delaware River Basin if the current moratorium imposed by the Delaware River Basin Commission were to be lifted. This ban has kept gas companies out of the Delaware River Basin to date but without a permanent ban, the basin could be opened.

The RiverKeeper Network commissioned a comprehensive study by CNA Analysis and Solutions, an independent, non-partisan, non-profit research firm, of what could happen to the region if the Delaware River Basin is opened up to fracking.

The Delaware River, the 400 mile long free flowing river that forms the western border for our community, is perpetually at risk from natural gas extraction companies because it sits on top of the Marcellus Shale, the second largest gas field in the country.

The Potential Environmental Impact from Fracking in the Delaware River Basin comprehensively details the potential environmental impacts broken into categories of land, water, and air.

Land use required by the extraction process would cause a reduction in core forest areas, significant in a densely populated area that cannot afford more habitat destruction and loss of carbon storage.
Local watersheds would also be degraded due to the amount of water used in the extraction process.
Wastewater discharges of some key contaminants posed significant risks and increased erosion rates would contaminate the river headwaters.
Billions of cubic feet of methane gas would be added to the atmosphere annually and nitrous oxide creating smog would dangerously decrease air quality in a region that now has clean, high air quality.

This report adds needed weight to the growing body of scientific studies on the potential detrimental impacts of fracking. Read the report and then add your voices to those opposing hydraulic fracturing along our western boundary and tell the Delaware River Basin Commission to make the fracking ban permanent.
