Society today consumes a huge amount of energy. As second- and third-world countries progress and first-world countries integrate more technology into their lifestyles, conservation efforts are not enough to slow energy consumption. Fossil fuels, such as natural gas and oil, are increasing in importance. Nuclear energy continues to be important, even through some countries, such as Germany, have announced plans to replace it with renewable energy sources Renewable energy sources continue to improve and will be important in the future energy portfolio. Microspheres and microcapsules have long been used in the pharmaceutical, food, cosmetic, chemical and livestock feed industries. Advances in energy generation technology call for new approaches to maximize efficiency and safety. This article discusses how microspheres and microcapsules can offer new solutions for solar, nuclear, and oil and gas recovery technologies.
