Green energy is any energy type that is generated from natural resources, such as sunlight, wind or water. It often comes from renewable energy sources although there are some differences between renewable and green energy, which we will explore, below.
Energy remains one of the critical challenges of the future. Businesses need to strike the balance between operational efficiency and sustainable development. With soaring energy prices and increased scarcity of natural resources, pinpointing energy efficiencies – from planning to manufacturing to operations - makes good business sense.
One way of reducing energy costs is to become more energy efficient so as to optimize existing resources and plan the right investments in new technologies. This will help manage operating costs and provide better delivery of services to customers while reducing environmental impacts and mitigating risk. Additionally, a documented commitment to sustainable development is a powerful and effective way to demonstrate social responsibility and meet changing customer preferences.
WAYS TO SWITCH TO GREEN ENERGY
Five critical actions needed worldwide to jumpstart the energy transition: treat renewable energy like an essential public good; secure, scale up and diversify the supply components and raw materials for renewable energy technologies; build frameworks and reform fossil fuel bureaucracies; shift subsidies away from fossil fuels; and triple public and private investments in renewables.

GOING GREEN ……………
The potential of renewable energy sources is enormous as they can in principle meet many times the world's energy demand. Renewable energy sources such as biomass, wind, solar, hydropower, and geothermal can provide sustainable energy services, based on the use of routinely available, indigenous resources.
Renewable energy sources currently supply somewhere between 15 percent and 20 percent of the world's total energy demand. The supply is dominated by traditional biomass, mostly fuel wood used for cooking and heating, especially in developing countries in Africa, Asia and Latin America. A major contribution is also obtained from the use of large hydropower; with nearly 20 percent of the global electricity supply being provided by this source.
New renewable energy sources (solar energy, wind energy, modern bio-energy, geothermal energy, and small hydropower) are currently contributing about two percent. A number of scenario studies have investigated the potential contribution of renewables to global energy supplies, indicating that in the second half of the 21 st century their contribution might range from the present figure of nearly 20 percent to more than 50 percent with the right policies in place.
