         Renewable Energy                 

 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

Renewable energy replaces conventional fuels in four distinct areas, electricity generation, hot water and space heating, motor fuels, and rural (off-grid) energy services

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

UN General Assembly declared 2012  the International Year for Sustainable Energy

.

Main forms of renewable energy

Wind power

Hydropower

Solar energy

Biomass

Geothermal energy

 

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

Energy Efficiency - Life Matters

Wind energy boom

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

Tidal power

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

Garbage dumpSweden'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, that there is simply not enough trash. Only 4 percent of Swedish garbage ends up in a landfill, according to Swedish 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 nearly 70 percent of deep sea Arctic creatures are in contact with human trash like plastic bags and beer bottles. In the US, where the EPA says 250 million tons of trash was generated in 2010 alone, only about 34 percent was recycled

Goodbye to one of solars biggest advocates Sad to hear that Larry Hagman, the former star of the hit TV show “Dallas” died over the weekend. In 2010 he said that his decision to install solar panels on his ranch in California came shortly after the great blackout of 2003. Originating in Ohio, the outage caused half of the eastern seaboard to lose power for as many as 3 days. Hagman went solar after that event reducing his utility bill from more than $37,000 a year to only $13
