Intermittent renewable energy sources such as wind, solar, run-of-river hydro, tidal streams and wave fluxes present interesting challenges when exploited in the production of electricity, which is then integrated into existing and future grids. We focus on wind energy systems because they have...

As a renewable energy source, wind power is gaining popularity as a favoured alternative to fossil fuel, nuclear and hydro power generation. In Europe, countries are required to achieve 15% of their energy consumption from wind by 2010 as the EU strives to meet its Kyoto obligations. Wind power...

Land degradation is a particularly vexing problem in developing countries; as forests are depleted, crop residues and dung are used for fuel, which degrades cropland. In Ethiopia, the government encourages tree planting and adoption of energy efficient stove technologies to mitigate land...

The carbon flux from burning biomass for energy is often legislated, or simply assumed, to be carbon neutral as subsequent forest growth sequesters carbon lost during energy production. In this sense, there may be no net contributions to atmospheric carbon flux associated with biomass energy....

This paper serves to document the REPA Forest Trade Model – a global model of forest trade that consists of ten products across two horizontal layers in a vertical chain. The model includes 20 regions: Five Canadian regions (Atlantic Canada, Central Canada, Alberta, BC Interior and BC Coast),...

British Columbia’s natural gas industry is currently facing competitive pressures from other gas-producing jurisdictions in North America. The emergence of shale gas developments has resulted in natural gas prices falling dramatically. Nonetheless, British Columbia is positioned to take...

A linear programming model is used to examine the impact of carbon taxes on the optimal generation mix in the Alberta electrical system. The model permits decommissioning of generating assets with high carbon dioxide emissions and investment in new gas-fired, wind and, in some scenarios, nuclear...

British Columbia’s energy policy is at a crossroads; the province has set a goal of electricity self-sufficiency, a 93% renewable portfolio standard and provincial natural gas strategy that could increase electricity consumption by 2,500-3,800 MW. To ascertain the reality of BC’s supply...

Power interruptions are a typical characteristic of national grids in developing countries.Manufacturing, processing, refrigeration and other facilities that require a dependable supply of power, and might be considered a small grid within the larger national grid,employ diesel generators for...
