Life Cycle GHG Emissions of Energy Transition Materials and Equipment

Life Cycle GHG Emissions of Energy Transition Materials and Equipment

Substitution of materials, equipment and low carbon fuels for high carbon fuels is underway and moving forward faster in some countries and economic sectors than others.  Substitution of manufactured equipment for fuels adds “life cycle carbon” to historical and on-going GHG emissions.  To what extent do GHGs emitted in creating low carbon energy economies retard overall decarbonization progress?  Life cycle carbon emissions for the years 2020 through 2029 add up to a minimum of 35 billion metric tons of CO2-eq, or roughly a year’s worth of current global energy related GHG emissions.  Overall life cycle carbon emissions will continue to increase after 2029 at least until direct global GHG emissions are brought under control. 

Integrated Implementation of Community Solar and Community Choice

Integrated Implementation of Community Solar and Community Choice

California and other states need a way to capture the environmental and economic benefits of community solar. Other states have found a way. California’s CCE industry should ask the California legislature to consider allowing California CCEs to use all or a portion of annual CPUC mandated PCIA charges to put local renewable projects on an equal economic footing with projects that require new high voltage transmission capacity to deliver electricity locally. This will increase CCE capacity and flexibility to address local energy resilience needs and to provide equitable access locally to the environmental and economic benefits of solar electricity.

California Energy Democracy's Last Stand

California Energy Democracy's Last Stand

California has ramped up a seventy-six billion dollar investment in all types of solar generation capacity over the past decade. California’s retail solar industry enabled half of the total investment. Rooftop solar has been a bright spot for California’s renewable energy transition even as state regulators and California utilities continue to make other energy democracy enablers - community choice, community solar, community microgrids - hard or impossible to finance.

Regulators are now considering rule changes that impose punitive “grid access” fees on rooftop solar adoption, plus drastic reductions in compensation for electricity that feeds into the grid from rooftop solar arrays. The future of energy democracy in California hangs in the balance.
