The emission of carbon dioxide and other relevant greenhouse gases has led to global warming with unpredictable but potentially catastrophic consequences. When fossil fuels are burnt they emit toxic pollutants that damage the environment and human health. Recent development in renewable energy technologies could help reduce the price of energy and related environmental concerns. Hydrogen could be used as fuel cells and sun for PV panels which are generally considered cheaper and more viable to the environment. There is a strong relationship between energy, environment and sustainable development. As such, these three cannot be separated from one another. Our environment needs to be protected from the effects of burning fossil fuels that result in the release of greenhouse gases such as NOx, SOx and CO2 which all of them could lead to global warming. Some of the areas with major concerns include acid rain, stratospheric ozone depletion, global climate change (greenhouse effect), water pollution, radiation and radioactivity, hazardous air pollutants etc. Therefore, achieving SDG-7 which deals with the attainment of the global quest for universal access to affordable, reliable, sustainable, and modern energy by 2030 cannot be possible unless significant effort is made. These include several solutions to the global energy and environmental problems which include; a breakthrough in renewable technologies, energy conservation, energy storage technologies, recycling and energy source different from fossil fuels.
