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.

Introduction to Solar Energy

Introduction to Solar Energy

Colin Palmer

40 years: Renewable energy

A tenfold cost reduction over the last ten years has caught many unaware, and solar PV is now set to be the largest source of renewable energy in the future. In this video, Colin explains how the conversion of sunlight to electricity in solar panels helped the industry develop. He further explains why and how solar energy generation will become ubiquitous.

Introduction to Solar Energy

13 mins 47 secs

Overview

The heating effects from focussing the sun’s rays have long been understood and during the early 20th century the photovoltaic effect was explained. By the mid 1950s, practical solar cells could be made, but the costs were extremely high. Continued development resulting in performance improvements and cost reductions, to the extent that by the first years of the 21st century, electricity from solar cells was becoming viable for large scale uses. The resulting market pull drove further cost reductions, to the point where, in may locations today, solar power is the lowest cost source of electric from any source.

A tenfold cost reduction over the last ten years has caught many unaware, and solar PV is now set to be the largest source of renewable energy in the future.

Key learning objectives:

  • How did the industry develop?

  • How is sunlight converted to electricity in solar panels?

  • Describe the make-up of the cost of solar PV power systems

  • Explain why and how solar energy generation will become ubiquitous
