Coral reefs are great tourist attractions. Nearly a million species of fish, invertebrates and algae live in these biodiversity hotspots and they generate billions of dollars yearly from the tourism industry.
The U.S. recently celebrated the milestone of having one million solar installations nationwide. It took 40 years to get there, but experts believe the next million could take only a couple of years. The solar revolution is clearly well underway.
California leads the nation in the use of solar energy with well over half the country’s solar electric capacity. The state is the home of several of the largest thermal solar generating plants in the world and between those and multiple utility-scale photovoltaic plants, California utilities get more than 5% of their power from the sun.
When we think about solar power, we mostly think about rooftops covered with solar panels. And indeed, there are more than 800,000 solar rooftops in the U.S. and the numbers are growing.
Crocodiles are large aquatic reptiles that live throughout the tropics in Asia, Africa, the Americas, and Australia. The first crocodiles appeared approximately 240 million years ago – around the same time as dinosaurs. And while the resilient species did survive the last great extinction, crocodiles might not be climate change-proof after all.
We are all familiar with the solar panels that cover an ever-growing number of rooftops as well as large arrays in so-called solar farms. These photovoltaic systems turn sunlight directly into electricity. But they are not the only way to make electricity using the sun.
One of the largest solar power plants in the world is the Andasol plant situated on a barren, high-altitude site in the Andalucia region of Spain. The plant provides electricity for up to 500,000 people in the region.
The use of solar power is growing rapidly but with all the growth, solar power only provides 1% of the country’s electricity. On the other hand, in 2014, solar power accounted for almost a third of all the new US electric generating capacity. According to the International Energy Agency, solar power could be the world’s leading source of electricity by the year 2050.
