Climate change may alter building energy demand. Here, the authors quantify changes in residential electricity and natural gas demand in Los Angeles County and find that rising temperatures may increase electricity demand by 41–87% between 2020 and 2060, but improved efficiency could lower this increase to 28%.
Intermittent renewable sources provide an ever-greater share of electricity, which changes the variability of the net load. This study models different renewables combinations over different timescales for the Nordic power system and shows how the optimal mix depends on the frequency band of the fluctuations.
Large-scale adoption of electric vehicles will only occur if the needs of individual drivers are met. Here the authors present a model of the energy consumption of personal vehicles in the USA, allowing an evaluation of the adoption potential of electric vehicles.
The recent drop in oil prices is having a profound impact on global energy markets, raising questions about how these markets might evolve over the long term. This study uses scenarios to assess the energy and emissions impacts of diverging oil price futures and which uncertainties they depend upon.
Reducing energy usage is important for climatechange mitigation. This Perspective focuses on the use and promise of agent-based modelling to understand the complexities of energy demand, including consumer behaviour.
For uptake of electric vehicles to increase, consumers' driving-range needs must be fulfilled. Analysis of the driving patterns of personal vehicles in the US now shows that today's electric vehicles can meet all travel needs on almost 90% of days from a single overnight charge.
Combined water and power models are important to predict how changes in one resource will impact the other. A new global assessment of hydropower and thermoelectric power plants predicts future vulnerabilities arising from climate-change-induced water constraints and tests possible adaptation options.
The need for new energy storage is often seen as an obstacle to integrating renewable electricity into national power systems. Modelling shows that existing technologies could provide significant emissions reductions in the US without the need for storage, however.
