This free online course will introduce you to energy use and the impact it has on the atmosphere and climate change. This will include some basic calculations for energy use and an introduction to some renewable energy technologies. You will learn how possible it is to get away from carbon-based energy sources and see if we can use other, sustainable sources to meet our energy requirements without negatively impacting the atmosphere. You will learn about the importance of energy in the social, economic and technological development of the world. You will study the concept of energy, its origins, its sources and the consequences of its consumption. You will also learn what sustainable development is, the dimensions it covers, the indicators it occupies and its importance for the future of humanity.

At this beginning of this course, you will learn the difference between unconventional energy, renewable energy and clean energy and the different types of clean energy available. Later in the course, you will learn about conventional energy sources such as oil, coal, natural gas, electricity. You will then study unconventional energy sources, also called “clean energies”. These will include generating energy from biomass, from the sea, from small hydroelectric facilities, wind, geothermal, solar and nuclear energy. Then, you will study energy consumption by country, by sector, and by population group. You will learn how statistical knowledge provides clarity on energy use, energy production, and energy shortages. Then, you will examine the details of energy consumption and supply within each sector, such as industrial, transportation and households.

Finally, you will learn about the alarming impact the current methods of generating energy has on the earth and its significant effect on the environment. This impact is producing changes that were not present for the first 400,000 years on this planet. You will learn how understanding the relationship between energy and environment is essential for sustainable development. The effects of the demand for environmental resources, especially water, food and fuel, and the drastic increase in population and the rate of consumption will be looked at. The consequences of such changes and possible solutions will be reviewed after. This free course is aimed at students, professionals and the general public who want to deepen their knowledge about the various sources of energy that exist and are being investigated in the world.
