This has been a very active year for the renewable energy sector. Many changes and developments have spawned great hope for further progress and global expansion of the renewable energy industry as one of the main sources of clean energy and ecnomic development in the future. Even though Cop15, one of the main events of the year, has resulted in moderate progress, we hope 2010 will bring more exciting changes, and a major turn towards renewable energy as a goal for all nations.

Several renewable energy technologies have shown great progress, and are on their way to becoming a major part of the renewable energy industry mix. These are primarily geothermal energy and marine energy. Several start-up companies from these sectors have emerged as promising future players, and we've already seen successful demonstrations of these technologies around the world, with investors slowly but steadily showing more interest in these technologies.

The already established renewable energy sources, such as wind, solar and hydropower, have also seen significant developments. The wind sector has shown progress in technology, with innovative designs and a major push towards bigger wind turbines, capable of generating 6+ MW of power at peak generation times. Even bigger machines have been announced, reaching 10 MW of capacity. Solar energy has had tremendous success in improving conversion efficiencies for photovoltaic solar power, reducing the cost of PV solar significantly, as well as improvements in solar thermal energy conversion, with new heat storage technology, and better efficiencies in converting sunlight into heat.  Even more importantly, solar energy has become a competitive alternative to traditional energy sources.

All these developments, along with renewable energy plan commitments by many countries around the world, lead to a very promising new year. Even if these plans are deemed unrealistic by sceptics, and are prone to changes, the big picture sill remains – renewable energy is on its way to become a major source of energy in 2010, and beyond.

Together with the industry, we at Renewbl.com have also had an exciting year. We've put in great efforts and long hours on building a website that is useful and informative to our readers. We have experienced growth, and would like to use this opportunity to thank everyone who has visited our site over the past year. In the new year, we are planning to introduce more interesting content sections on the site, but we won't stop there – there are plans for further developments which we hope will be interesting.

We hope Renewbl.com will remain a useful source of information for you in 2010.

All the best in the new year!
