##  Energy 

Improving energy efficiency and supporting the increased use of non-carbon-emitting energy sources are key to our vision of making a positive contribution to society’s efficient use of energy. 

In 2012, we implemented initiatives across our operations aimed at improving our energy efficiency. For example, at our steelmaking coal operations we are replacing haul trucks with trucks using an upgraded, more efficient electric drive system. The newer trucks can haul 33% more material with only 10% more horsepower. At four of our steelmaking coal operations in B.C., we have significantly reduced emissions associated with the coal-drying process by switching to natural gas in the dryers. This has led to an overall reduction of emissions of 35%. Going forward, we will be identifying more opportunities to improve efficiency, reduce power use and cut emissions. 

The Wintering Hills Wind Power Facility near Drumheller, Alberta completed its first full year of operation in 2012. Teck has a 30% interest in this project, which is a joint venture with Suncor Energy, the project operator. Wintering Hills performed better than expected, producing 88 gigawatt hours (GWh) of electricity — enough clean power to provide over 57,000 tonnes of CO$_{2}$-equivalent credits, which offsets greenhouse gas emissions from our Cardinal River Operations in Alberta. 

## Saving Energy 

We have set a long-term goal of implementing projects that reduce energy consumption by a cumulative 6,000 terajoules at our existing operations — enough to power close to 60,000 homes. 

##  Materials Stewardship 

The materials that we produce are essential to improving the quality of life for people around the world. As demand increases and new supplies of metals and minerals become more challenging to develop, we are focused on creating the maximum value for society from our products with the minimum impact on people and the environment. 

We are conducting life cycle assessments of our products to ensure that we maximize their value and minimize their environmental effects. This includes developing a better understanding of key aspects of our products from utility through to end of life and recycling. 

Teck is also a leader in recycling. Our Trail Operations processed approximately 11,700 tonnes of lead from battery products in 2012, equivalent to approximately 1.6 million car batteries. We also continued to build on our electronic waste (e-waste) recycling program, which recovers useful metals from end-of-life electronics. Trail Operations also processed 12,000 tonnes of e-waste in 2012, reducing waste and keeping metals and plastics out of landfills.
