Half of all existing conventional electricity generating plants in the US will need to be replaced by 2030 as they reach the end of their useful life. The question is, what should they be replaced with? The Rocky Mountain Institute has studied this question and concluded that investing in distributed renewable energy makes the most economic sense.
“Renewables and DERs are outcompeting and beginning to capture market share from natural gas-fired generation in many parts of the country, including both peaking capacity, as well as higher-efficiency, combined-cycle plants,” Mark Dyson of RMI and an author of the report tells Solar Industry Magazine.
“The consequences of continuing a business-as-usual approach — building new gas generation when clean energy technologies are increasingly winning the day — promises to negatively impact customers, investors and the environment through higher energy costs; the risk of stranded assets; and greater carbon and air emissions.”
This is an issue that economists can really dig their teeth into. A generating plant typically has a useful life of 50 years. That means a natural gas plant built today will have economic and environmental consequences for the next half century.
None of the economic analysis that natural gas advocates proffer in support of their proposals contain one dime’s worth of consideration for the social costs of the carbon dioxide emissions they will create over their 50-year life. It’s easy to say one plan is cheaper than another if you don’t have to figure in all the costs associated with it — like killing every living thing on the earth in pursuit of profits.
But you can’t say that in a debate. It’s too controversial. And besides, the corrupt capitalist model that now rules the world makes privatizing profits and socializing costs something to be rewarded, a goal to strive for. It is so common, nobody notices any more. Just business as usual. Nothing to see here. Move along. People who dare to point out the emperor is wearing no clothes are pilloried and marginalized as kooks and extremists. As if killing people for profit is not an extremist thing to do! But I digress.
The Rocky Mountain Institute has released a new study it says shows distributed renewable energy is ready today — right now this very minute — to shoulder the burden of providing reliable electrical energy to the US and do it for the same or less money than the natural gas generating plants that are on the drawing board. The report says renewables beat new gas generating facilities on levelized costs and are steadily eroding the profitability of existing gas facilities. And they can provide the same level of reliability as conventional generating facilities.
RMI says, “US electricity generators may be committing their customers and investors to as much as $1 trillion in future investment and fuel costs through 2030 as they rush to build new gas-fired power plants. Yet advances in renewable energy and distributed energy resources (DERs) offer lower rates and emissions-free energy while delivering all the grid reliability services that new power plants can.”
