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.

Why Clean Energy is Inevitable II

Why Clean Energy is Inevitable II

Richard Black

In this video, Richard unpacks the unstoppable momentum behind the global clean energy transition, revealing how plummeting costs and massive investment shifts are rapidly sidelining fossil fuels. He dives into real-world evidence showing renewables outcompeting coal, oil, and gas. He also explores the wide-ranging benefits of clean energy, including economic growth, energy independence, public health, and global stability.

Why Clean Energy is Inevitable II

12 mins 39 secs

Key learning objectives:

  • Understand how falling costs and investment trends are accelerating the transition to clean energy

  • Identify the economic, social, and geopolitical benefits of the clean energy transition

  • Outline the role of government policies in determining the speed of the energy transition

Overview:

The clean energy transition is happening at unprecedented speed, driven by plummeting costs of renewables, battery storage, and electric vehicles. Wright’s Law explains how scaling production lowers costs, making wind, solar, and storage cheaper than fossil fuels. The shift brings lower energy prices, cleaner air, energy security, and economic opportunity. China and Europe lead the way, while fossil fuel industries face decline. The future is clean, but political and financial action will determine how fast we get there.

Summary
What real-world evidence shows that clean energy is replacing fossil fuels?

The cost of solar, wind, and battery storage has dropped dramatically, with solar alone by 85% in a decade. Wind and solar now make up a third of global electricity generation, and in countries like Germany, solar is already cheaper than fossil fuels even with battery storage. Investments are shifting, with 90% of new electricity investment going to renewables. In transport, EVs are rapidly reaching price parity with petrol cars, and global oil demand is set to peak this decade.

How does the clean energy transition benefit economies, societies, and global security?

The shift to clean energy means lower and more stable energy prices, millions of new jobs, and massive health benefits from reduced air pollution. It also diminishes the influence of petrostates, which tend to have higher military spending and lower investment in social goods. Countries can achieve energy independence by generating their own renewable electricity rather than relying on fossil fuel imports, reducing risks of geopolitical blackmail and economic instability tied to oil and gas markets.

Which countries are leading the energy transition, and what challenges remain?

China leads in renewable deployment, battery production, and EV manufacturing, while Europe is aggressively expanding clean energy after cutting dependence on Russian gas. India’s renewables sector is poised for rapid growth. However, outdated regulations, slow permitting processes, and fossil fuel lobbying still pose barriers. Governments must streamline approvals, resist industry pushback, and reform financial systems to fund clean energy expansion in developing nations. The transition is inevitable, the speed at which it happens is the key question.
