The Science of Climate Change

Climate change is no longer a distant threat or just a possibility, it is now a reality for all of us. In this pathway, Kevin Trenberth, a renowned climatologist, delves into the science behind climate change. He first introduces the climate system, its main components and forces.

Tackling the Plastic Crisis

Plastic pollution is by far the biggest threat to our oceans and this remains an incredibly tough problem to solve. Plastic credits could potentially serve as one of the much needed solutions for this crisis.

The Scale of the Net Zero Challenge

The price of meeting net zero is estimated to be between $100-150 trillion over the next 30 years. Regardless of this cost, we need to reach net zero before climate change does irreversible damage to the environment and the economy.

ESG, Sustainability and Impact Jargon Buster

ESG, sustainability, impact… they all just mean green, right? Not quite. Despite being used often interchangeably, there are distinct differences between these terms.

40 years: Renewable energy

Energy from the wind has been used by mankind for thousands of years, but has become outdated since the early twentieth century. Join Colin as he explains why there was a revival in wind energy in the 1907s and how the industry developed. He further talks about the square-cube law and its relevance to wind turbines.

Introduction to Wind Energy

15 mins 41 secs

Overview

Energy from the wind has been used by mankind for thousands of years, but had become outdated by the early twentieth century. It needed the oil price shock of the mid 1970s to renew interest in this technology, and by the 80s there were thousands of new wind turbines in operation, mainly in Europe and the USA.

After considerable government backed research and commercial development, the industry settled on the “Danish model” design, with three blades made of composite materials, rotating on the upwind side of a steel tower. Over time the average size of wind turbines increased, from around 30m diameter in the early 1980s to as much as 240m today. Power output has increased from 350kW to 15MW.

The cost of wind turbines has reduced over time and continues to do so. In many parts of the world, electricity from wind turbines is now competitive with fossil fuel generation.

Key learning objectives:

  • Why was there a revival in wind energy in the 1907s?

  • How did the industry develop?

  • What has become the industry standard design, and why?

  • What is the square-cube law and why is it relevant to wind turbines?
