Sustainable energy solutions are becoming increasingly important in the face of climate change and dwindling natural resources. Here are ten vital statistics that can help you understand the current landscape of sustainable energy.
As of 2021, renewable energy sources accounted for 29% of global electricity generation. This marks a significant increase from just 18% in 2010, highlighting the shift towards sustainable solutions. Source: International Energy Agency
Solar power capacity has expanded by more than 20% annually in the last decade. As of 2021, installed solar power capacity globally reached over 800 GW. Source: REN21
Wind energy has the potential to provide up to 20% of global electricity needs by 2030, as per estimates. Currently, wind power contributes around 7% to the global electricity generation. Source: WindEurope
According to the International Renewable Energy Agency (IRENA), the cost of solar photovoltaic (PV) systems has dropped by 82% since 2010, making them cheaper to install than coal and gas-fired power plants. Source: IRENA
The renewable energy sector employed around 11.5 million people in 2018, with the number projected to rise to 24 million by 2030 as demand grows. Source: International Labour Organization
Energy storage systems, particularly batteries, are essential for balancing supply and demand in renewable energy. The global energy storage market is expected to grow from $7 billion in 2018 to $16 billion by 2024. Source: Forecast International
Hydropower is the largest source of renewable electricity, providing approximately 16% of global electrical energy. In 2021, its contribution was roughly 4000 TWh. Source: International Hydropower Association
Geothermal energy is a sustainable and reliable source, yet it only accounts for about 0.5% of global energy consumption. Its full potential could provide up to 13% of total global energy needs. Source: Geothermal Energy Association
Improving energy efficiency can reduce greenhouse gas emissions by nearly 70% by 2050. Investment in energy efficiency could save the global economy $18 trillion by 2030. Source: International Energy Agency
Studies show that ambitious governmental policies are crucial for the transition to sustainable energy. Countries that have implemented policies aimed at reducing carbon emissions see a 30% increase in renewable energy investments. Source: UN Environment Programme
Understanding these facts is essential for grasping the urgency of transitioning to sustainable energy solutions. As the world moves towards a more sustainable future, staying informed and engaged can help us all contribute to this vital cause.
