Energy and how it converts to power is a never-ending exploration for scientists. The most significant issue concerning energy right now is how to store it, especially for long periods of time. It's possible to get solar energy from the sun, but what happens to the energy when it's not a sunny day? There's also the problem of having enough space to hold all of this energy. Listen to learn how scientists are trying to figure out how energy can be stored long-term to power the things we use every day.

To lower dependency on fossil fuels, some Americans have installed solar panels on their homes to produce their own clean energy. This decision involves a cost-benefit analysis of cost value and environmental impact. In some regions this cost-benefit ratio has been upset by fracking, and the cheap natural gas that it produces. How does supply and demand impact the cost of energy? How does the cost of energy impact people seeking alternatives such as solar energy? Listen to learn how one family has dealt is dealing with this shifting energy landscape.

As nations look for clean energy alternatives, many are turning to wind and solar, but Indonesia is turning to its volcanoes. Indonesia has 130 active volcanoes. These volcanoes generate geothermal heat that is released through vents and hot springs throughout the country. Power companies are learning to harness and redirect this heated steam into power plants in order to generate electricity. Indonesia’s geothermal energy potential is huge, but start up costs and oil subsidies might prevent this burgeoning clean energy from taking off.
