The Environmental Disaster of Solar Energy

 Written by John Hinderaker    in EnergyEnvironment    on August 15, 2019    Print

Solar energy is terrible for the environment in a number of ways, including the fact that large land areas must be devoted to it. At Forbes, Michael Shellenberger highlights another problem with solar energy: it produces vast quantities of hazardous waste, which are not being adequately dealt with.

The last few years have seen growing concern over what happens to solar panels at the end of their life. Consider the following statements:

* The problem of solar panel disposal “will explode with full force in two or three decades and wreck the environment” because it “is a huge amount of waste and they are not easy to recycle.”

* “The reality is that there is a problem now, and it’s only going to get larger, expanding as rapidly as the PV industry expanded 10 years ago.”

* “Contrary to previous assumptions, pollutants such as lead or carcinogenic cadmium can be almost completely washed out of the fragments of solar modules over a period of several months, for example by rainwater.”

All of these statements come from solar industry insiders. Cadmium is a particular toxic waste problem:

The fact that cadmium can be washed out of solar modules by rainwater is increasingly a concern for local environmentalists like the Concerned Citizens of Fawn Lake in Virginia, where a 6,350 acre solar farm to partly power Microsoft data centers is being proposed.

“We estimate there are 100,000 pounds of cadmium contained in the 1.8 million panels,” Sean Fogarty of the group told me. “Leaching from broken panels damaged during natural events — hail storms, tornadoes, hurricanes, earthquakes, etc. — and at decommissioning is a big concern.”

This is how OSHA describes cadmium:

Cadmium and its compounds are highly toxic and exposure to this metal is known to cause cancer and targets the body’s cardiovascular, renal, gastrointestinal, neurological, reproductive, and respiratory systems.

Disposal of decommissioned solar panels in regular landfills is “not recommended in case modules break and toxic materials leach into the soil.” But where do most decommissioned panels go? Landfills. Recycling is often recommended, but is not practical because “recycling costs more than the economic value of the materials recovered, which is why most solar panels end up in landfills.”

Worse, many decommissioned solar panels which were supposed to be properly disposed of are instead labeled “used” and sold to Middle Eastern countries that have no ability to deal with hazardous materials like cadmium.

Some might ask, don’t all sources of energy involve hazardous wastes? Perhaps, but the volume of waste produced by solar panels and wind turbines vastly exceeds that associated with reliable power sources, as this chart shows:

Solar panels rarely produce electricity–never at night, not much when it is cloudy, and in a Northern climate, not when they are covered with snow and ice. In Minnesota, solar panels produce electricity less than 20 percent of the time. The intractable problem of hazardous waste disposal associated with solar panels is one more reason why they are a terrible investment.

Hungry for Change; Solar Panels are not on the Menu

By: Herb Eckerlin

United Nation scientists met in Geneva, Switzerland last week to shed new light on the global warming issue.  They have concluded that human-caused climate change is dramatically degrading the Earth’s land, and the way people are using the land is making global warming worse.

These conditions are creating a vicious cycle that is making food more expensive, scarcer and less nutritious.

The UN scientists believe that humanity must change the way it uses the land to avoid “world hunger.”  Given that reality, why are we covering arable farmland to build solar power plants that cover thousands of acres?

In light of the scientists’ conclusions, can you think of anything more irresponsible? 

Removing farmland from agricultural production is not a gradual process like the effect of global warming on the land, it is instantaneous.

The UN scientists have sent us a warning.  It is: “You had better change your ways before you do any more damage.”  As NASA climate scientist Cynthia Rosenzweig has stated, “The cycle is accelerating.” 

The threat of climate change and the improper use of agricultural land will affect our future food supply and create, in the scientists’ words, a “Hungry Future.”    

We have to find another way to address the Global Warming problem, and preserve our future food supply. Placing solar panels on agricultural land is simply making matters worse …. much worse.  Let us heed the warning of these scientists.  

To avoid a “Hungry Future,” we had better change our ways and stop taking farmland out of agricultural production.

Shedding light on solar’s true energy potential

By: Herb Eckerlin 

The generation and distribution of electrical energy is a complicated business. Most people don’t give it a lot of thought. For example, if the light switch works, they move on. If it doesn’t, they panic and call the local power company.

…But what if “not working” becomes a regular occurrence, what then? This question may become more common in the future.

Solar power is intermittent and not reliable. Therefore, with a 100% solar system, the light switch will only work some of the time. Is that acceptable? Are our fellow citizens aware of this liability? People have to be informed of this liability.

Where does the electricity come from?

Most of it is generated at plants powered by fossil fuels (like natural gas and coal) and nuclear energy. Smaller amounts of power may come from hydro, solar and wind.

Where it comes from is of little concern to many, the more important question is, “Will the light switch come on?”

Local utility companies like Dominion and Duke Energy have the responsibility to generate the power and deliver it to your switch. We have come to expect it.

But, with intermittent solar power, this is often not the case.

Electrical power is generated in large central stations (also called power plants) rated in Megawatts. A 900 megawatt plant is not uncommon. It has the capability of generating 900 megawatts continuously, all day long (24/7).

The point here is this: Natural gas, coal and nuclear plants are reliable …. They can deliver 900 megawatts at any time of day or night. That cannot be said for a 900 megawatt solar plant. It can only deliver 900 MW for one hour at noon on a sunny day. That’s a huge difference.
