Trophically balanced sustainable agriculture

Schramski, J.R.; Rutz, Z.J.; Gattie, D.K.; Li, K. - In: Ecological Economics 72 (2011) C, pp. 88-96

Considering an economy without fossil fuels, literally built from the ground, then up, we developed several interactive research models of biointensive farms that use no fossil fuels. Quantifying and summarizing total human labor–energy input and total caloric energy output, we demonstrate...

Energy issue perception, responses and solutions from green economics: a discussion paper

Armstrong-Haworth, Benjamin - In: International Journal of Green Economics 3 (2009) 3/4, pp. 351-366

We currently rely on fossilised energy to power society. This comes at a cost, not only in financial terms, and not only to us as human beings, but also in non-financial and non-human terms. Among the concerns of green economists are the cost of energy as opposed to its price, high levels of...

Is what we think of as “rebound” really just income effects in disguise?

Saunders, Harry - In: Energy Policy 57 (2013) C, pp. 308-317

This paper examines the question of whether unexpectedly high energy use in the wake of energy efficiency gains can be explained as arising from increases in consumer wealth, as opposed to energy efficiency rebound effects. The analysis concludes that historical energy consumption increases were...

Multi-megawatt wind turbines for offshore use: aspects of Life Cycle Assessment

Tryfonidou, Rodoula; Wagner, Hermann-Josef - In: International Journal of Global Energy Issues 21 (2004) 3, pp. 255-262

Life Cycle Assessment (LCA) is an instrument to quantify environmental impacts of the entire energy supply chain. According to the LCA, an appropriate indicator system should comprise all steps of a system's life cycle: production, operational and disposal processes ("cradle-to-grave")....

Life cycle assessment of a solar thermal collector: sensitivity analysis, energy and environmental balances

Ardente, Fulvio; Beccali, Giorgio; Cellura, Maurizio; … - In: Renewable Energy 30 (2005) 2, pp. 109-130

Starting from the results of a life cycle assessment of solar thermal collector for sanitary warm water, an energy balance between the employed energy during the collector life cycle and the energy saved thanks to the collector use has been investigated. A sensitivity analysis for estimating the...

Life cycle assessment of two different 2 MW class wind turbines

Guezuraga, Begoña; Zauner, Rudolf; Pölz, Werner - In: Renewable Energy 37 (2012) 1, pp. 37-44

Although wind technology produces no emissions during operation, there is an environmental impact associated with the wind turbine during the entire life cycle of the plant, from production to dismantling. A life cycle assessment is carried out to quantify the environmental impact of two...
