Are Wind and Solar Energy Really More Expensive and Less Dependable?

Not that long ago, critics of eco-friendly sources of energy had a point when they declared wind and solar power cost more and were less reliable than fossil fuels, mostly because they rely on the wind blowing and the sun shining.
That is changing. The constant progression of scientific accomplishments are making wind and solar as affordable to produce as nonrenewable fuel sources, and significantly competitive at keeping energy as well.
” The myths about sustainable energy are based upon rates and efficiency that are usually out-of-date,” stated Bruce Usher, a professor of professional practice at Columbia Business School, where he teaches on the intersection of monetary, environmental and social concerns.
Developments have both improved performance and reduced expenses, said Steven Cohen, former veteran executive director of the Earth Institute at Columbia University and now senior vice dean the Universitys School of Professional Studies.
” Just as we saw with computer systems, the more time engineers invest on these issues, the much better the technology becomes,” he stated.
The myth abides.
Renewables vs. Extreme Weather
In spite of claims to the otherwise, renewables are no less trusted than other source of power during severe weather condition events.
In Texas, which is the only state with its own power grid, Gov. Greg Abbott falsely blamed wind and solar energy for last winter seasons failure of the states energy grid throughout extreme storms that saw power generation interrupted and natural gas pipelines freeze. Former Energy Secretary Rick Perry overdid, claiming that the event exposed the danger of relying of renewable resource.
A federal study in fact discovered that eco-friendly sources exceeded nonrenewable fuel source production during the occurrence, which was mainly triggered by failures of devices improperly protected from the freezing temperatures, regardless of the energy source. National Public Radio concluded it was a systemwide failure to prepare for extreme cold.
Cohen said the case in Texas was also eventually a failure of guideline.
” Due to the deregulated nature of the Texas power system, windmills which can quickly be secured from cold were not protected,” he said. “Windmills in northern Europe and the U.S. have no issue operating in the cold.”
In California, other critics of renewables made similar claims last summer season during heatwave-related blackouts, even after a state study (PDF) found that the main causes were environment change-induced severe weather, insufficient resources and preparing processes, in addition to market practices– all unassociated to renewables.
” In California the issue has also been old transmission equipment, which causes forest fires and then is damaged throughout fires,” Cohen said.
Maybe the typical denominator among the energy failures brought on by a frozen Texas and a blistering California is that neither state is prepared for the obstacles presented by climate modification.
Approaching Better Storage and Transmission
In California, the primary problem wasnt an absence of power generation, however inadequate investment in batteries to save wind and solar power.
Usher points to developments in battery innovation as what has made eco-friendly energy more reliable.
” Wind and solar have actually always been trustworthy generators of power,” Usher stated, “when its windy and warm.” It was the storage half of the formula that, in the past, made them less reputable.
” Wind and solar projects are increasingly being combined with energy storage– mostly in the type of batteries– making sustainable sources more trusted by attending to the intermittency of wind and solar power generation,” Usher said.

Together with more and better storage, both professionals determined another secret to increasing sustainable energy production: moving the electrical power from where it is created to where it is required. High-capacity transmission lines will help, Cohen stated.
Funding the Future of Energy
Usher said that federal government tax rewards can play an important function beforehand battery technology and upgrading energy infrastructure, for instance. But Cohen believes the totally free market is the larger engine here.
Most of the resources will originate from energy utilities and consumers who will gain from a more trusted and effective energy system once renewables, microgrids and dispersed generation of energy is integrated with wind and solar farms, he said.
Cohen noted in a recent blog post that were currently seeing a rise in climate-friendly stocks and a declining interest in fossil fuel companies, which are losing ground to renewable resource companies in drawing in new capital.
However, neither expert predicts renewables filling in fossil fuels whenever soon.
” I believe the concept that there is some number or fast fix is delusional,” Cohen stated. “This is a shift that will take a generation to complete.”
Usher includes that “Anyone who thinks renewable power isnt the future of energy isnt taking a look at the fundamental patterns that are almost specific to produce strong tailwinds for the industry for the next 30 years: lower expenses plus increasing need from electric automobiles and demand to decarbonize. The energy shift from nonrenewable fuel sources to renewables will likely happen, but over 30 years, not overnight.”
