With global energy demand continuously on the rise, fossil fuels alone will not be sufficient to meet the demand. Alternative energy, which is defined as any energy source other than fossil fuels, is gaining interest domestically and internationally. This segment addresses a lot of concerns linked to fossil fuel usage, including carbon-dioxide emissions, climate change, and other harmful effects on the environment. Companies operating in the alternate energy space include business operations in products, services, and research associated with alternative energy, and in production and supply of alternative energy. As development in technology continues amid high fluctuations in oil prices, this sector is expected to see high volatility.
