Solar power was just a niche application 10 years ago. Many people liked the idea of solar power, but it was too expensive for all but a small percentage of the population. Now, solar power is cost-competitive with other electricity options for hundreds of millions of people. The biggest challenge is simply making people aware of that.
Renewable energy is massively important for so many reasons. The most prominent of them is the greatest challenge modern civilization has faced -- global warming and climate change. However, renewable energy also helps to improve political stability in many regions, helps to clean the air and water, helps to boost local and national economies, and helps to provide energy security and reliability.
Since the middle of 18th century, mankind has been using fossil fuel energy as a bank account, from which we collectively withdraw every year using a peculiar sort of ATM.
Wind power and solar power together now produce as much electricity in Germany as nuclear power. In the first half of 2014, each of them produced 45 TWh of electricity. Wind power produced 26.7 TWh while solar produced 18.3 TWh.
Almost anywhere you go, even taking into account extra emissions from dirty power plants, electric cars are greener than conventional cars powered by gasoline or diesel fuel. However, people are constantly adding renewable energy power plants to the grid, which means that electric cars are constantly getting greener.
Our Planet is not doing very well. Desertification, devastating storms, droughts, flooding, loss in biodiversity and many more increasingly worrying environmental / climate change related threats. Why are we not changing this? Do we have the power, the strength to change? Do we care?
While current energy outlooks to 2030 and beyond retain a dominant role for fossil fuels in the world’s energy mix, simple mathematics indicate that at the current pace of renewable energy investment (~0.3% of global GDP) the energy available to humans at the end of the century will be a small fraction of the current..
Energy outlooks to 2030 and beyond indicate growing global energy demand and a continued dominant role for fossil fuels in the world’s energy mix, even as utilization of renewable energy sources expands rapidly…
Renewable energy is entering a period of uncertainty that mirrors the increasing uncertainty about oil prices. Will increased demand from China and revitalized Western economies maintain oil prices at current levels in the face of increased supply from fracking and possibly from Iran? If so, government support for renewable energy should remain strong. If oil prices fall, however, then as in the 1980s many governments may cut their investments in new energy technologies so that alternative energy sources are unavailable when oil prices rise again. What can we do now to ensure continuing support for renewable energy initiatives in the face of possible short term economic and political pressures?

In the clean energy revolution, much attention gets put on China, the US, and Europe. These are, of course, very big and influential markets, and it's good to see each of them promoting clean energy in their own ways, but focusing on them so much sometimes leaves out other inspiring stories, like South Korea's cleantech story.READ MORE
Iceland may not command much of the global economy, but it is known for clear leadership in a few arenas. One of those is energy, as the country gets ~85% of its energy from renewable sources.READ MORE
One of the things I love about the Zayed Future Energy Prize is that it has introduced me to numerous cleantech leaders I hadn’t previously heard or read about. It especially does this for me in one particular segment of the cleantech market: companies and organizations serving the developing world.READ MORE
The Zayed Future Energy Prize Review Committee met in Abu Dhabi on September 1 and 2, 2014, to compile the short list of entries for the Selection Committee. During the meeting, we sat down with one of the longest-serving Committee members, Philip Moss, Senior Advisor at Mana Ventures, a clean tech accelerator based in Masdar City, to ask for his views on the evaluation process and the significance of the Prize.READ MORE
A lot of focus gets put on technological breakthroughs and “potential breakthroughs.” Solar technology is no exception. In fact, it seems that potential solar technology breakthroughs get hyped more than almost anything else. The fact is, there’s a lot of solar research going on around the world. Almost everyone in the energy business is aware that solar has a huge future ahead of itself, and there are many people and companies trying to carve out their share of that market.READ MORE
Following up on my articles on the history of solar power science, history of solar power policy, history of solar power manufacturing, history of wind turbines, and history of trains, here's a piece on the history of electric cars. However, for a little bit of alliteration, I titled it the "evolution of electric cars."READ MORE
