Renewable energy could provide up to 80 percent of the electricity demands for the US by 2050. The estimate is based upon various assumptions including the advancement of technology and an increased demand for electricity.
Wind generated electricity is already a competitive scenario and is expected to be a major source of renewable energy in the decades to come.
The cost of producing energy via wind or solar has seen a significant drop due to advancements in the technologies and increasing consumer demand.
As we rapidly move forward into the age of renewable energy, many countries are starting to invest in the technology as a means of meeting their long term carbon emissions commitments.
The United States could be getting 80 percent of its electricity from renewable sources by 2050 and all it would take is doubling the pace for installing renewable energy sources and then doubling it again and somewhere between $320 billion and $1 trillion – on top of a baseline $4 trillion in investments.
Of course, the costs and the pace of renewable energy will depend upon the demands for power and the rate of technological change for wind, solar and geothermal power.
Those, in a gross over-simplification, are the findings of the “Renewable Electricity Futures Study” – a monumental, four-volume, 865-page opus – by the National Renewable Energy Laboratory in Golden.
The “80 percent by 2050” made a little bit of a pop in the news, but reporters moved on pretty quickly, for truth told, this study wasn’t written for journalists but policymakers.
The report is an intricate assembly of scenarios: low-demand, high-demand, 30 percent renewable energy to 90 percent renewable. Even the central 80 percent scenario comes in three flavors – no technological improvement, incremental improvement and evolutionary technology – under three different transmission scenarios….More at Renewable energy could provide 80% of US electricity – but at what cost? – Denver Post (blog)
