In this paper the case for subsidies for solar energy to counter inefficient pricing practices of electric utilities, hidden subsidies to non-solar fuels and tax law biases are examined. The conclusion reached for two of three regions in the USA in the case of solar energy replacing electricity for hot water heating is that, far from offsetting biases against solar energy, current subsidies reinforce pre-existing biases in favour of the use of solar energy systems.
This article proposes eco-protective countermeasures that may serve as theoretical reference for post-mining eco-rehabilitation of the Xiangshui coal mining area, Guizhou, China. These countermeasures were developed from baseline survey and assessment data for the eco-environment including plant communities, soil types, physical and chemical properties, water and soil loss, status quo, etc.

The data contain yearly modeled estimates of Pacific salmon escapement (in annual metric tons of wet mass) from 1976 to 2015 across four regions of western North America. A second data file contains modeled estimates of contaminant or nutrient concentrations in Pacific Salmon. The modeled estimates were derived from Bayesian generalized linear models (contaminant or nutrient concentrations) or from Bayesian generalized additive models (Salmon Escapement).

This paper investigates the potential for systematic errors in the Energy Information Administration’s (EIA) widely used Annual Energy Outlook, focusing on the near- to midterm projections of energy demand. Based on analysis of the EIA’s 22-year projection record, we find a fairly modest but persistent tendency to underestimate total energy demand by an average of 2 percent per year after controlling for projection errors in gross domestic product, oil prices, and heating/cooling degree days. For 14 individual fuels/consuming sectors routinely reported by the EIA, we observe a great deal of directional consistency in the errors over time, ranging up to 7 percent per year.

Biomass remains a key energy source for several billion people living in developing countries, and the production of liquid biofuels for transportation is growing rapidly. However, both traditional biomass energy and crop-based biofuels technologies have negative environmental and social impacts. The overall research challenge for bioenergy is to develop the technologies to produce useful products at low costs while minimizing the use of scarce resources such as arable land and water. This requires substantial advancements in modern biomass power generation and the success of liquid biofuel technologies that permit the use of lignocellulosic feedstocks or possibly algae. With such technologies, biomass resources...
