The world is experiencing
an energy revolution to rival the invention of the steam engine. A
whole range of clean renewable energy technologies are available.
They include not just solar and wind power but also tidal, wave,
hydro, geothermal, biofuels and ground source heat exchangers. We
need clean energy sources to replace fossil fuels such as coal and
oil, which produce greenhouse gas emissions and cause global
warming
. The UN's International Panel on Climate Change also identified energy
efficiency as the quickest and easiest way to reduce
greenhouse emissions. It is estimated that a third of all
energy we use is waisted
With the world’s population reaching
seven billion, and nine billion by 2030, demand for energy resources
is becoming a critical economic and security factors for world
leaders. But these challenges would also provide enormous business
opportunities for both governments and the private
sector
Renewable energy flows involve natural
phenomena such as sunlight, wind, tides, plant
growth, and geothermal heat. It is derived from natural processes that
are replenished constantly. In its various forms, it derives
directly from the sun, or from heat generated deep within the earth.
Included in the definition is electricity and heat generated from
solar, wind, ocean, hydropower, biomass, geothermal resources, and
biofuels and hydrogen derived from renewable resources
When we put a priority on renewable energy we
address job creation, climate change, women's empowerment and food
security. Sustainable energy cuts across nearly every major
challenge we face today and will face in the
future.
Australia like most countries, has an abundance of solar,
wind, wave and other clean
energy sources. Using energy more efficiently will conserve energy
use, avoid waste and working smarter can save money and conserve and
preserve the environment
Renewable energy provides 19 per
cent of electricity generation worldwide. Renewable power
generators are spread across many countries, and wind power alone
already provides a significant share of electricity in some areas,
for example 14% in the US state of Iowa, 40 per cent in the
northern German state of Schleswig-Holstein, and 20 per cent in
Denmark. Some countries get most of their power from renewables,
including Iceland, Paraguay, Norway, Brazil, Austria, New Zealand,
and Sweden
.
Heating
Solar hot water makes an important
contribution to renewable heat in many countries,
most notably in China, which now has 70 per cent of the
global total. Most of these systems are installed on multi-family
apartment buildings and meet a portion of the hot water needs of an
estimated 50 to 60 million households in China. Worldwide, total
installed solar
water heating systems meet a portion of the water heating
needs of over 70 million households. The use of biomass for heating
continues to grow as well. In Sweden, national use of biomass energy
has surpassed that of oil. Direct geothermal for heating is also
growing rapidly
.
Transport fuels
Renewable biofuels have contributed to a
significant decline in oil consumption in the United States since
2006. The 93 billion liters of biofuels produced worldwide in 2009
displaced the equivalent of an estimated 68 billion liters of
gasoline, equal to about 5 per cent of world gasoline
production
.
Energy Efficiency?
Energy can be used more efficiently This means we can conserve our use of energy,
taking steps to avoid waste when using. It means being smarter
by working out how to get the same outcomes while using less
energy
Improving energy efficiency has multiple
benefits including, lowering carbon
pollution improving energy security and helping
households and businesses cope with rising energy prices. Improving
energy efficiency does not mean limiting economic growth or reducing
living standards, it means only being smarter about how to
use energy at home and at work. A range of policies is already in
place to help Australians save on energy bills. Under the
Government’s plan for a Clean
Energy Future these efforts are continuing with new
initiatives adopted
Wind energy is the fastest growing large
scale renewable energy source in Australia. It supplied around two per cent of
Australia’s overall electricity
needs in 2010.This clean, renewable source provided energy equivalent to
the electricity used in a year by over 700,000
homes.The Clean Energy Council indicated there was an additional
9,000 megawatts of large scale wind farm
projects proposed for development around the country. Around
1,000
megawatts of new capacity is currently under
construction
South Australia
is successful
Integration of wind energy generation into the electricity grid in
SA is a success story. The gross statistic often quoted is the total
electricity produced as a percentage of the supply. In the
year to June 2012, the electricity generated by
wind farms amounted to 26per cent of the total supply. This was
behind the 50 per cent supplied by natural gas and ahead of coal at
24 per cent
.
Wave Energy Generators
Australian States of Vic, NSW and SA are
trialing wave energy generators and will connect to the grid in late
2013. Every generator will power over 1000
homes
Wave energy to power homes Worlds first wave
energy project which mimics the movement of seaweed and kelp through
the water. It will power thousands of homes in Victoria Australia

Sweden's wants your trash This small
Nordic country is breaking records with its waste program of
generating energy from garbage which is wildly successful. But
recently its success has also generated a surprising issue,
thatthere is simply not enough trash. Only 4 percent of Swedish
garbage ends up in a landfill, according toSwedish Waste Management Due to its
efficiency in converting waste to renewable energy, they have
recently begun importing around 800,000 tons of trash annually from
other countries.Sweden is leading pthe way in waste management, but
it is one of few. We live in a world where nearly70
percent of deep sea Arctic
creaturesare in
contact with human trash like plastic bags and beer bottles. In the
US, where theEPA says
250 million
tons of trash was generated in 2010 alone, only about 34 percent was
recycled
