| Summary: | Energy-efficient projects use alternative technologies, fuels and management
systems to reduce heat and electricity consumption. Renewable energy-supply
projects produce heat and electricity using sources of energy which are regenerated
over short time periods. Their recent rise to prominence in modern
society has been driven by their low environmental impacts relative to
fossil-fuelled alternatives. However, as they mature, energy-efficient and
renewable energy technologies must demonstrate not only their environmental
benefits but also their economic competitiveness. This book focuses
on the assessment of projects using approaches that take into account the
unique economic, environmental and energy characteristics of renewable
and energy-efficient technologies.
The global demand for energy-supply and efficiency projects has never
been greater. Between 2012 and 2035, the demand for primary energy and
electricity is estimated to increase by half and 70%, respectively, mainly
in developing countries, while in developed countries the ongoing shift
to energy-efficient and low carbon supply technologies are projected to
continue. These trends are driven by many – mostly inescapable – factors: a
growing global population, increasing wealth, uncertainty of fossil fuel price,
security of supply concerns and enhanced policies to combat greenhouse
gas (GHG) emissions and global warming. For example, by 2013, China, the
European Union (EU) and Japan had adopted emission-reduction targets,
while California, Australia,New Zealand and the EUhad introduced carbon
emissions trading schemes. Assuming the implementation of such existing
policy commitments only, it is projected that between 2010 and 2035, a $37tn
investment will be required in the world’s energy-supply infrastructure and
as much as $11.8tn will be spent on energy-efficient measures across all
economic sectors (IEA, 2012).
