What progress has the world made in the last few centuries? Why? Padlet – Progress

How does your class compare to psychologist Steven Pinker?

How has the world’s population grown so much in the last few centuries? What does the world need to do to manage the growing numbers?

One solution for many of the challenges above is for all people to have access to efficient and cheap energy. Think about this statement, how does access to energy help people go forward or improve their lives?

Types of Energy

Before working out solutions to developing methods for efficient and cheap energy, let’s look at what types we use in the world today.

Wind

  • How do we harness the power of wind?

Key question: Is wind efficient? Is it cost-effective? What are the advantages and disadvantages of wind power?

Conclusions

When thinking about which is the best, most efficient, cheap or type of energy that has the least environmental impact, consider which parts of the world will be more suitable to your choices. Does the developed world (HIC) require the same energy as the undeveloped (LIC) for example?

What are the possible consequences of altering the types of energy the world currently uses?
