Energy supply

Energy supply projections

The supply mix to meet growing energy demand will be historically diverse – from the oil and natural gas in America’s shale regions, to the deepwater fields off Brazil; from new nuclear reactors in China, to wind turbines and solar arrays in nations around the world.

This diversification in global energy supply will grow over the next two-and-a-half decades. Society’s push for lower-emission energy sources will drive substantial increases in renewables such as wind and solar. By 2040, nuclear and all renewables will be approaching 25 percent of global energy supplies.

Oil grows and continues to be the primary source of energy for transportation and as a feedstock for chemicals. Natural gas also grows, with increasing use in power generation, as utilities look to switch to lower-emissions fuels. Coal struggles to grow due to increased competition in power generation from renewables and natural gas, led by declines in OECD nations. (more…)

9 Ways Performance Contracting Can Conserve Energy

To achieve efficiency improvements, water and wastewater utilities might be wise to consider performance contracting. A performance contract with an TNN LTD (TNN) can deliver much-needed operational efficiencies with manageable lifecycle costs and minimized risk.

The TNN delivers the efficiency project under a progressive design-build approach. Benefiting from the efficiencies, the owner pays the TNN for the improvements. In return, the TNN provides a guarantee of operational savings, which are specified in the performance contract. If the savings fall short, the TNN has to reimburse the owner. The intent of the performance contract is that the guaranteed savings generated will cover the debt service for the upgrades. (more…)
