Financial advisory and asset management firm Lazard released its eighth annual report Levelized Cost of Energy Analysis, showing that renewable energy can compete with coal, natural gas and nuclear power plants on a cost basis. Couched in the cautious language of risk/benefit analysis, it said, "Certain alternative energy generation technologies are cost-competitive with conventional generation technologies under some scenarios."
The report warned that unpredictable factors they could nor or did not examine "could have a potentially significant effect on the results," including things like "the social costs and rate consequences for those who cannot afford distribution generation solutions, as well as the long-term residual and societal consequences of various conventional generation technologies that are difficult to measure (e.g., nuclear waste disposal, environmental impacts, etc.)." But its findings suggest that defenders of fossil fuel power generation will have a harder and harder time falling back on the economic costs and "it's too expensive" to justify resistance to renewable energy.
The report said that while U.S. federal tax subsidies are "an important component of the economics of alternative energy generation technologies," they may not be essential, as the cost of wind- and solar-generated power continues to decline, especially in areas of strong sun or wind. It found that energy costs for some renewable technologies have dropped about 15 percent in the last year and about 60 percent in the last five years, and predicts that advances in technologies like battery storage will continue to drive cost declines. The falling costs will likely encourage more investment in renewable technologies on its own even without subsidies, according to London's Financial Times.
"We find that alternative energy technologies are complementary to conventional generation technologies, and believe that their use will be increasingly prevalent for a variety of reasons," said the report.
“We used to say some day solar and wind power would be competitive with conventional generation," George Bilicic, global head of power, energy and infrastructure at Lazard, told the Financial Times. "Well, now it is some day.”

The Centers for Disease Control has emphasized that washing hands with soap and water is one of the most effective measures we can take in preventing the spread of COVID-19. However, millions of Americans in some of the most vulnerable communities face the prospect of having their water shut off during the lockdowns, according to The Guardian.
Aerial photos of the Sierra Nevada — the long mountain range stretching down the spine of California — showed rust-colored swathes following the state's record-breaking five-year drought that ended in 2016. The 100 million dead trees were one of the most visible examples of the ecological toll the drought had wrought.
Now, a few years later, we're starting to learn about how smaller, less noticeable species were affected.

Disinfectants and cleaners claiming to sanitize against the novel coronavirus have started to flood the market, raising concerns for the U.S. Environmental Protection Agency (EPA), which threatened legal recourse against retailers selling unregistered products, according to The New York Times.
The global coronavirus pandemic has thrown our daily routine into disarray. Billions are housebound, social contact is off-limits and an invisible virus makes up look at the outside world with suspicion. No surprise, then, that sustainability and the climate movement aren't exactly a priority for many these days.
