Storing Heat From The Sun
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.
Carbon Capture Update
The global community is increasingly making commitments to reduce the amount of carbon emissions in the atmosphere. More and more carbon-free renewable energy sources are being used all the time. But despite the tremendous growth in solar and wind power, fossil fuels still provide about 80% of the world’s energy. Coal still provides about 40% of worldwide electricity. Realistically, these numbers can only go down at a relatively gradual pace.
Responding To Climate Change
This week, representatives of 195 nations and the 28 member states of the European Union are meeting in Paris to try to put together the first global agreement to curb carbon dioxide emissions. Among those nations, some are already doing much better than others.
A Tax On Carbon
A while back we talked about the carbon tax in British Columbia and how it resulted in a dramatic reduction in carbon fuel use without any harm to the local economy. Many economists believe that carbon taxes are one of the best ways to promote lower greenhouse gas emissions.
Cities Abandoning Fossil Fuels
Around the world, cities are trying to combat climate change by shifting their energy needs away from coal, oil and natural gas. Some, like Reykjavik and Zurich, use no fossil fuels to produce power at all; others are still planning cutbacks.
