Clean Energy
Clean energy refers to energy generated from renewable sources that produce minimal to zero greenhouse gas emissions during operation. Key forms of clean energy include solar, wind, hydroelectric, geothermal, and tidal power, alongside biomass and nuclear energy, which, while not renewable, is recognized as carbon-free. As the world confronts the pressing challenges posed by climate change and environmental degradation, transitioning to clean energy sources has become increasingly vital. These alternatives not only help mitigate climate change by reducing reliance on fossil fuels, such as coal and oil, but also contribute to energy security and sustainability. Recently, advancements in technology have propelled clean energy to the forefront of the global energy conversation. Solar power, in particular, has seen extraordinary growth, accounting for a significant portion of new electricity generation capacity worldwide, driven by innovations like next-generation solar cells and energy storage solutions. The growth of clean energy is further bolstered by supportive policies and substantial investments, with funding for both solar and battery sectors experiencing record highs. In fact, projections suggest that overall clean energy investment could reach an unprecedented $2.2 trillion, reinforcing the role of renewables as pivotal to achieving a sustainable energy future. The rising demand for clean energy is coinciding with increased electrification across transportation, heating, and industry sectors, further underscoring its relevance in contemporary energy discourse. As countries strive to reach net-zero emissions and combat air pollution, clean energy is set to become a cornerstone of economic recovery and resilience, presenting opportunities for job creation and technological advancements essential for a sustainable future.

Watch clip answer (03:01m)What is Neom and what are its key features?
Neom is an ambitious futuristic city project being developed in the Saudi Arabian desert. The planned linear city will stretch 170km and is designed to run entirely on renewable energy and artificial intelligence. The project aims to attract 10 million residents, comparable to the population of New York City, all living within this innovative urban development in the desert landscape. This $1.5 trillion megaproject represents Saudi Arabia's vision for a technologically advanced urban center that integrates sustainable energy solutions with cutting-edge AI systems, creating a completely new model for urban living in what was previously undeveloped desert terrain.
Watch clip answer (00:17m)What was the significant achievement of Solar Impulse in 2015?
In 2015, Solar Impulse made aviation history by completing a journey around the world powered entirely by sunlight. This groundbreaking aircraft demonstrated the potential of sustainable aviation technology through its historic circumnavigation. While Solar Impulse showcased what was possible with solar power, it has now paved the way for Bertrand Piccard's new Climate Impulse project, which aims to circumnavigate the globe in 2028 using green liquid hydrogen technology instead of solar power.
Watch clip answer (00:10m)What is Climate Impulse and what are its goals?
Climate Impulse is an innovative project that aims to circle the globe in 2028 using a lightweight two-seater aircraft powered by supercooled liquid hydrogen. Led by aviation pioneer Bertrand Piccard, the project's primary goal is to demonstrate the viability of hydrogen as a clean energy source for aviation. The aircraft is designed to complete its global circumnavigation with zero emissions, potentially revolutionizing sustainable air travel. With support from aerospace industry partners like Airbus, Climate Impulse represents a significant step toward decarbonizing the aviation sector, with test flights scheduled for 2026 before its nine-day non-stop journey around the world in 2028.
Watch clip answer (00:12m)How does the Climate Impulse aircraft aim to achieve zero-emission flight around the world?
The Climate Impulse aircraft utilizes green hydrogen produced through renewable electricity, which is then liquefied and stored in two large fuselage tanks. This innovative two-seater plane, piloted by Rafael Dinelli and Bertrand Piccard, aims to circumnavigate the globe non-stop over nine days while producing zero emissions. The design features a cockpit between the two massive fuel tanks, allowing sufficient hydrogen storage for the complete journey. By powering flight with green hydrogen rather than conventional fossil fuels, Climate Impulse demonstrates the viability of sustainable aviation technology that could revolutionize the industry's approach to decarbonization.
Watch clip answer (00:31m)What solution does Bertrand Piccard believe will lead to clean aviation?
Bertrand Piccard is convinced that liquid hydrogen will be a key solution for clean aviation in the coming years. While the immediate future involves sustainable alternative fuels—combinations of fossil and non-fossil fuels—to begin decarbonizing the industry, hydrogen represents the path to achieving much cleaner aviation long-term. The aviation sector faces urgent pressure to reduce carbon emissions, and while sustainable alternative fuels offer a transitional solution, Piccard emphasizes that liquid hydrogen technology will ultimately enable a more comprehensive transformation toward truly sustainable air travel.
