Environmental Sustainability and Energy Challanges

About This Environmental Sustainability course

This online course in Environmental Sustainability and Energy Challenges from Harvard University will expose you to the core issues of “sustainable development”and climate change. You will from renown Harvard professors how Environmental sustainability issues  is addressed in the world today, and how reliable and sustainable energy solutions can be created for human societies.

Humanity faces an immense environmental and energy challenge: providing abundant energy to everyone without wrecking the planet fixed resources. If we want a high-energy future while protecting the natural world for our children, we must consider the environmental consequences of energy production and consumption. But money matters too: energy solutions that ignore economic costs are not realistic—particularly in a world where billions of people currently can’t afford access to basic energy services. How can we proceed?

Energy Within Environmental Constraints won’t give you the answer. Instead, we will teach you how to ask the right questions and estimate the consequences of different choices.

This course is intended for a diverse audience. Whether you are a student, an activist, a policymaker, a business owner, or a concerned citizen, this course will help you start to think carefully about our current energy system and how we can improve its environmental performance.

This course:

  • Covers engineering, environmental science, and economics to enable critical, quantitative thinking about our energy system
  • Focuses on a working understanding of energy technologies, rich in details of real devices and light on theory; you won’t find any electrodynamics here but will find enough about modern commercial solar panels to estimate if they would be profitable to install in a given location
  • Covers environmental impacts of the energy system, focusing on air pollution, climate change, and land use
  • Emphasizes costs: the cascade of capital and operating costs from energy extraction all the way through end uses
  • Emphasizes quantitative comparisons and tradeoffs: how much more expensive is electricity from solar panels than from coal plants, and how much pollution does it prevent?  Is solar power as cost-effective an environmental investment as nuclear power or energy efficiency?  And how do we include considerations other than cost?

Please note that this is an abridged course, equivalent to roughly half of a full semester-long undergraduate course.  See the syllabus for topics that we include and a list of some we exclude.

What you’ll learn

  • How energy flows through modern economies, from initial resources to end users
  • The environmental impacts of today’s energy system, focusing on air pollution, climate, and land use
  • How to estimate economic costs of reducing environmental impacts
  • Details on nuclear and solar power: technology, costs, policy, unique challenges and problems
  • How to critically compare energy options, including quantitative and qualitative analysis
