Modeling life cycle greenhouse gas emissions from photovoltaic and wind power generation, with and without energy storage
Several approximate findings are made on the carbon intensity of PV power. (1) Reversible temperature effects raise the carbon intensity of silicon PV power installed in warm regions, including by -10% in the southwestern US and ~13% in western India. (2) All temperature effects raise silicon PV …

Direct and Indirect Greenhouse Gas Emissions from Biomass Storage: Implications for Life Cycle Assessment of Biofuels
… biofuels may lead to underestimation of the carbon intensity of these fuels. Current life cycle assessment models of biofuels do not sufficiently account for biomass losses and emissions associated with the harvest and storage of biomass feedstocks, which can require additional fuel and …

Fuel cells for domestic heat and power: are they worth it?
Fuel cells could substantially decarbonise domestic energy production, but at what cost? It is known that these micro-CHP systems are expensive but actual price data has been elusive. Economic realities constrain individuals’ decisions to purchase and national policies on climate change, so this …
