Steel and concrete are fantastic materials that will continue to be fundamental in the future, but we cannot ignore their high energy costs and carbon footprint. As well as is expected a transition from fossils fuels to renewable energy sources, the change from fossil fuel-based building materials to renewables will also be inevitable in the future of construction.

Abstract A survey of 278 sawmills and other sources of wood residues in Georgia revealed that wood fuels were available at $3.86 to $5.69 per ton FOB, the source. Unsold wood residues were available in volumes necessary to meet the needs of 7 of 14 firms considering use of wood fuels. If these nonforest product firms converted to wood fuels, the savings in annual energy costs would range from 23 to 57 percent, depending upon the fossil fuel currently being used. However, other firms would have to either pay prices higher than $6 per ton for wood residues or purchase logging residues in order to generate the supply of wood fuels necessary to meet their requirements.


Subject Declining costs of renewable energy. Significance Recent auctions and 'levelised cost of energy' (LCOE) studies show that the costs of wind and solar photovoltaic power are now competitive with fossil-fuel power generation in an increasing number of scenarios. Impacts Competitive renewable energy costs will encourage governments to adopt renewables as first-choice technologies. While positive for emissions, higher renewables adoption will slow growth in international fossil fuel trade to the detriment of exporters. Variable renewable energy growth will increase demand for system-balancing technologies, such as interconnectors and electricity storage.

This paper examines the potential that exists for energy conservation in feeding livestock and poultry in the Northeast by analyzing the “What if” question: “What if national policy dictates using imputed energy “costs” to minimize energy use in feed rations?” Current feed rations contain large amounts of embodied energy reflecting the quantity of fossil fuel energy required to produce, process and transport the various ingredients included in the feed rations. By changing the mix of ingredients in feed rations, perhaps considerable energy could be saved in the Northeast.

Concerns about the effect of CO2 emissions on climate change and rising energy costs have renewed the interest in efficiency improvement in fossil fuel use as well as the utilization of locally available low or moderate temperature heat sources, such as geothermal or solar. This paper summarizes twenty years of Ormat’s very significant achievements in developing cycles, configurations and equipment for electricity generation from low grade waste heat and water dominated geothermal resources. As of the end of 2007 some 30 plants ranging from 200 kW to 130 MW totaling about 1000 MW are in operation.
