Renewables can help to reduce
GHG emissions, study notes
CANBERRA, Australia,
September 5, 2007.
The widespread adoption of renewable energy technologies has the
potential to considerably reduce the growth in greenhouse gas emissions and
to improve energy security, according to a consulting firm in Australia.
“With energy consumption in APEC economies projected to increase by 140%,
investment in technologies to reduce GHG emissions is crucial,” says Phillip
Glyde of ABARE, commenting on the study ‘Energy Security, Clean Technology
Development and Climate Change.’ The report estimates that, with the world's
best policies to stimulate the rapid take-up of low-emission technologies,
the level of emissions could be reduced by half.
APEC economies account for half of the world’s energy use, economic
output and GHG emissions, and one third of the world’s population. Under
current policy settings, energy consumption in APEC economies is projected
to increase by 140% by 2050, by which time GHG emissions will be 130% higher
in APEC economies relative to 2004 levels.
The widespread adoption of cleaner, more advanced and energy efficient
technologies has the potential to considerably reduce the growth in
emissions and those investments could reduce emissions by 49% relative to
baseline predictions, the study notes. If current policy settings continue,
energy supply in the APEC region by 2050 would come 31% from oil, 29% from
coal, 25% from gas, 9% from nuclear, 2% from hydroelectricity, 3% from
biomass and 1% from all other renewables.
Under an ‘enhanced technology’ scenario, sources of energy supply would
be 29% from oil, 18% from gas, 16% from coal, 14% from nuclear, 3% from
hydroelectricity, 15% from biomass and 5% from other renewables. The report
includes high efficiency photovoltaic power, large advanced wind generators,
biomass gasification plants, geothermal hot rocks and tidal power to be
renewable energy sources.
“Various supply, infrastructure and cost constraints prevent any one of
these technologies from addressing the climate change challenge on its own,”
it notes. “For that reason, a portfolio of these technologies will be
necessary to lower, both significantly and cost effectively, the emissions
intensity of electricity generation.”
Primary energy consumption under the ‘enhanced technology’ development
and deployment scenario would be 32% lower in APEC economies at 2050 than
would otherwise be the case. Under this scenario, consumption of fossil
fuels would fall considerably, as would greenhouse gas emissions.
“The regulatory environment, which may include taxes and subsidies, can
also reduce investment in energy efficiency measures or low emission
technologies through their influence on the expected returns from using such
technologies,” it continues. “As a result, investments in energy saving
technologies are also lower than the socially optimal level. Energy pricing
policies in several developing economies, for example, have been identified
as an impediment to the development and uptake of renewable energy
technologies.”
“APEC can continue to play an active role in reducing barriers to the
development and uptake of energy efficient and renewable energy technologies
and in developing appropriate funding models through the Energy Working
Group, Business Advisory Council, APEC committees and senior officials and
leader meetings and processes,” it adds. “Appropriate levels and methods of
funding for capacity building and technology development and transfer will
differ between APEC economies depending on individual country circumstances.
In some economies, direct government funding for technology research,
development and demonstration in collaboration with industry partners will
be the preferred policy approach. However, in other economies, revenue from
implementation of market based instruments to encourage GHG abatement may be
used to fund technology development, demonstration and transfer.”
