Clean Energy Technologies
In this lecture, you will explore the five main clean energy sources — solar, wind, hydro, geothermal, and biomass — along with the supporting technologies that make the energy transition possible, such as smart grids, energy storage, and efficiency systems. You will also discover the role of electric vehicles and green hydrogen as emerging solutions, and understand how all of these connect to the UN Sustainable Development Goals and the European Green Deal.

Clean energy sources
Solar energy captures sunlight using photovoltaic panels or thermal systems. It is the fastest-growing energy source in Europe.Wind energy harnesses moving air through onshore and offshore turbines, generating electricity with zero CO2 emissions.Hydropower uses the force of flowing or falling water — one of humanity's oldest and most reliable energy sources.Geothermal energy taps into the Earth's internal heat, providing consistent 24/7 renewable energy unaffected by weather.Biomass converts organic materials (agricultural waste, wood chips) into heat and electricity as part of a circular economy.

Smart Grids, Batteries & Energy Efficiency
This paragraph is ready to be filled with incredible creativity, experiences, and stories.
Smart grids use digital technology to monitor and manage energy flow, balancing supply and demand in real time.Energy storage systems (lithium-ion, solid-state batteries) store surplus renewable energy for use when generation is low.Grid-scale storage enables higher penetration of intermittent sources like solar and wind without sacrificing reliability. Energy efficiency measures — in buildings, industry, and transport — reduce total demand, making the transition more achievable.Together, these technologies form the backbone of a modern, decarbonised energy system.

Title 2
Solar energy works through two main technologies. Photovoltaic (PV) panels convert sunlight directly into electricity using semiconductor cells, while concentrated solar power (CSP) systems use mirrors to focus sunlight and generate heat that drives a turbine. Europe's solar capacity has grown exponentially in the last decade, with countries like Spain, Germany, and Italy leading deployment. Spain alone enjoys over 300 sunny days per year in many regions, making it one of the most favourable locations for solar generation in the EU. The cost of solar PV has dropped by over 85% since 2010, making it the cheapest source of new electricity in most of the world.
Green hydrogen is produced through electrolysis — splitting water (H2O) into hydrogen and oxygen using electricity from renewable sources. When powered by clean energy, the entire production process is carbon-free. This distinguishes green hydrogen from grey hydrogen (produced from natural gas, which accounts for 95% of current global hydrogen production) and blue hydrogen (grey hydrogen with carbon capture). Green hydrogen has enormous potential for decarbonising sectors that cannot easily be electrified: steel production (replacing coal-based blast furnaces with hydrogen-based direct reduction), cement manufacturing, chemicals, long-haul shipping, and aviation. The EU's Hydrogen Strategy targets 10 million tonnes of domestic renewable hydrogen production by 2030. However, significant challenges remain: electrolysers are expensive, efficiency losses during production and conversion are substantial, and distribution infrastructure is still in its infancy. Storage and transport of hydrogen (either compressed, liquefied, or converted to ammonia) add further complexity and cost.
This lecture aims at presenting the fundamental clean energy sources and supporting technologies that are central to Europe's energy transition, providing learners with the scientific and technical foundations needed to identify and counter energy-related disinformation. Within the general architecture of the POWER educational platform, this lecture equips the target group with a solid understanding of how clean energy works in practice, enabling them to critically evaluate claims about renewable energy and recognise when factual information is being distorted or misrepresented. Therefore, the lecture is structured into four main parts: (1) an overview of the five main clean energy sources — solar, wind, hydro, geothermal, and biomass — and their key characteristics; (2) an introduction to the supporting technologies that make the energy transition viable, including smart grids, battery storage systems, and energy efficiency measures; (3) an exploration of emerging solutions such as electric vehicles and green hydrogen and their role in decarbonising hard-to-electrify sectors; and (4) an explanation of how these technologies connect to broader policy frameworks, namely the UN Sustainable Development Goals and the European Green Deal.
Main learning questions addressed:
- What are the main clean energy sources and how do they contribute to a sustainable energy mix?
- How do supporting technologies such as smart grids and energy storage enable a reliable clean energy system?
- What role do electric vehicles and green hydrogen play in the broader energy transition?
- How do European and international policy frameworks — the SDGs, the Green Deal, Fit for 55, and REPowerEU — drive the deployment of clean energy technologies?

Solar energy works through two main technologies. Photovoltaic (PV) panels convert sunlight directly into electricity using semiconductor cells, while concentrated solar power (CSP) systems use mirrors to focus sunlight and generate heat that drives a turbine. Europe's solar capacity has grown exponentially in the last decade, with countries like Spain, Germany, and Italy leading deployment.

Green hydrogen is produced through electrolysis — splitting water (H2O) into hydrogen and oxygen using electricity from renewable sources. When powered by clean energy, the entire production process is carbon-free. This distinguishes green hydrogen from grey hydrogen (produced from natural gas, which accounts for 95% of current global hydrogen production) and blue hydrogen (grey hydrogen with carbon capture). Green hydrogen has enormous potential for decarbonising sectors that cannot easily be electrified: steel production (replacing coal-based blast furnaces with hydrogen-based direct reduction), cement manufacturing, chemicals, long-haul shipping, and aviation. The EU's Hydrogen Strategy targets 10 million tonnes of domestic renewable hydrogen production by 2030. However, significant challenges remain: electrolysers are expensive, efficiency losses during production and conversion are substantial, and distribution infrastructure is still in its infancy. Storage and transport of hydrogen (either compressed, liquefied, or converted to ammonia) add further complexity and cost.
