Climate Change:
How Can Wind Energy Help?
Wind
energy plays an important role in addressing climate change on a global level.
Many countries around the world have been working hard to reduce their carbon
emissions during the last decades. Some of the world's leading markets in the
US, Denmark, Australia and the UK recognized the power of clean energy and
electricity to reduce carbon pollution.
By
increasing the proportion of electricity generated from wind energy we can
lower greenhouse gas emissions and reduce our dependency on fossil fuels. Wind
farms do not emit greenhouse gases when they generate electricity, in contrast
to coal and gas stations. An additional negative side in relation to both coal
and gas as sources of energy is the amount of wasted heat that cannot be easily
transformed into electricity. Almost half of the energy used to produce
electricity from gas and coal is lost during the production process, which is
not the case with wind energy.
Wind Energy In
Numbers
2015
brought good news for the wind sector and it seems like we will hear much more
about this industry. Wind energy assured its place in the future as the
inexpensive way of harvesting electrical power. As the emphasis on protecting
the environment is growing, wind power is looking better as an option for a
sustainable future.
2014
was an exceptional year for wind energy, but 2015 is bringing surprises in
terms of leading markets. Data obtained by GreenMatch and the Global Wind Energy Council indicate
that China will continue to lead the global market with a share of 40-45%.
Additionally, new markets, particularly in Latin America and Africa, will
emerge and Europe will continue its steady march towards its 2020 targets.
In
terms of numbers and installed capacity, North America is always the hardest to
predict. However, existing incentive arrangements and numerous projects planned
for 2015 and 2016 in North America are good indicators that the upcoming period
will most likely be good for the wind industry in this region. Although 80% of
the existing wind power installations are situated in Republican congressional
district, it remains the case that energy issues are ideologically positioned
in Washington.
When
it comes to the Pacific region, Australia is the only contributor to the
region’s wind energy production. Even though numbers are not reaching their
highest potential, Australia’s tremendous wind capacities indicate that this
market will get stronger.
In
the first quarter of 2015 following six countries had more than 10,000 MW of
installed capacity including China with 114,609 MW, the US with 65,879 MW,
Germany with 39,165 MW, Spain with 22,987 MW, India with 22,465 MW and the UK
with 12,440 MW. Looking ahead, the picture is complex across various regions
and the rest of 2015 is likely to be good period for wind energy.
Eyes on the
Future
Considering
all the benefits of wind energy, it is not surprising that it is a fast growing
industry. Although initial costs of installation are high, scientists are
constantly seeking for ways of reducing prices and developing new solutions.
One of them is the usage of existing offshore oil platforms that are nearing
the end of their useful life as an installation field.
Latest studies are showing high potential of new types of wind
turbines, capable of harnessing stronger and more consistent winds, higher in
the atmosphere. Even though these new models are in the testing phase, there
are high potential and positive results associated with their development.
Initial
costs of installations will most likely fall to compete with the affordable
traditional energy sources, as gas, even in low-wind regions. According to the
US Department of Energy, future plans are focused on reducing the prices of
land-based wind energy down by 18% and the cost of offshore wind energy by 63%
until 2020.
While
electricity from onshore wind farms is already cheaper than conventional power
in an increasing number of markets, relatively high costs remains the biggest
challenge for offshore wind development. In today’s rapidly shifting
environmental and energy policy landscape, an important goal of the wind
industry is to be pricing competitive with fossil fuels and affordable for not
only commercial but domestic markets.
