The advantages and limitations of solar photovoltaic (PV) systems for energy generation are reviewed under various physical efficiency limits and financial assistance programs. Recent increases in utility and fuel costs in poultry production as well as public awareness of and demand for green...

A preliminary feasibility study of the implementation of various absorption heat pump configurations in a Kraft pulping process has been performed. Three different cases were considered: (i) integration of a double lift heat transformer into the heat recovery circuit of the wood chips digesters...

The potential to liberate steam production capacity for power generation has been assessed using actual energy consumption data and the recorded seasonal consumption fluctuations for a kraft pulp mill. The revenues from power production are compared with possible energy savings, achieved through...

This paper presents results from a model of a representative wind power investor's decision making process using a Monte Carlo simulation of a project financial analysis. Data, in the form of probability distribution functions (PDFs) for key input variables were collected from interviews with...

In the United States, electricity consumers are told that they can “buy” electricity from renewable energy projects, versus fossil fuel-fired facilities, through participation in voluntary green power markets. The marketing messages communicate to consumers that they are causing additional...

Adequate supply of cleaner, affordable, and reliable electricity is critical for the growth and prosperity of any economy. The Government of Ontario, Canada's largest province both by population and by electricity generation capacity, has enacted a long-term energy plan in 2007 to ensure...

Keeping energy costs contained during a time of rising rates takes ingenuity, coordination, perseverance and educated staff. Facility managers at Pacific Northwest National Laboratory did not invent something new, they simply took advantage of resources that were already available to lower...
