Some people, such as Professor Jacobson at Stanford University in California, advocate the US can supply ALL of its energy needs, not just for electricity, from wind, solar and hydro. He calls it the WWS approach. Storage would be required for peaking, filling-in and balancing the variable, intermittent wind and solar energy.
That would mean shutting down nuclear, gas, coal and oil plants and replacing them mostly with wind and solar and storage.
Below is the…Continue

Based in the latest Greenhouse Gas Emissions Inventory Update 1990 - 2013, issued July 2017, it appears there has been an increase in CO2eq emissions from 8.378 million metric ton in 1990 to 8.745 MMt in 2013. The numbers for 2014, 2015, 2016, and 2017 likely were about the same as 2013. See table 1.…Continue

The usual custom among energy systems analysts is to make projections regarding future energy consumption and work back from those projections to what is required to meet them. Following business-as-usual practices, Brussels projects a doubling of Europe’s energy consumption by 2050, and that 60 - 80% of the energy generation in 2050 will be renewable, but likely not CO2-free.…Continue

My first reaction to the aerial photos of Fukushima power plant site was: why did they put the auxiliary transformers, that provide power to the plant, and the emergency diesel-generators, that provide power to the auxiliary transformers, on the OCEAN side? They should have been on the land side, protected from earthquakes, and out of reach of any tsunami.
The lack of emergency power to operate the cooling pumps caused the reactor cores to overheat, melt and evaporate and…Continue
