Energy & Environment

Energy moves the world, from powering vehicles and industries to providing electricity and heat to households. Commercially produced energy can be derived from a variety of sources, including fossil fuels, nuclear, and renewables. Fossil fuels have been the world’s choice since the Industrial Revolution, but because of their price volatility, and most importantly their direct relation to carbon emissions and climate change, many countries have started diversifying their primary energy sources, particularly to renewables.

Despite civilization’s dependence on nature for energy, food, and water, human activity has severely impacted the environment in recent centuries. Climate change has become the largest crisis ever faced by humankind. Carbon emissions, water pollution, and waste management are a few of the many environmental issues to be tackled in the coming decades.
