affordable clean energy
How bad is it?
Access to clean and affordable energy varies greatly around the world, and can be quite bad in some regions. According to the International Energy Agency (IEA), around 759 million people worldwide lacked access to electricity in 2019, with the majority of those living in sub-Saharan Africa and South Asia.
3 billion people rely on wood, coal, charcoal or animal waste for cooking and heating
Energy is the dominant contributor to climate change, accounting for around 60 per cent of total global greenhouse gas emissions
Since 1990, global emissions of CO2 have increased by more than 46 per cent.
Hydropower is the largest single renewable electricity source today, providing 16% of world electricity at competitive prices. It dominates the electricity mix in several countries, developed, emerging or developing.
Bioenergy is the single largest renewable energy source today, providing 10% of world primary energy supply.
will it get worse?
Carbon Brief analysis of the IEA figures shows that it expects global electricity generation to rise by 2,493TWh between 2022 and 2025. The IEA expects the growth in renewable generation to cover the vast majority of this total, growing by 2,450TWh. This is equivalent to 98% of the overall increase in global demand
One key factor is population growth. As the world's population continues to grow, particularly in developing countries, demand for energy is likely to increase as well. Without significant investments in clean energy infrastructure, this could result in increased reliance on fossil fuels and other non-renewable sources of energy, leading to greater environmental degradation and climate change.
Another factor is political and economic instability. In regions where there is political instability or conflict, energy infrastructure may be damaged or disrupted, making it difficult for people to access the energy they need. Similarly, economic instability or downturns could lead to reduced investment in energy infrastructure, making it harder for people to access affordable energy.
However, there are also many positive developments that suggest access to clean and affordable energy could improve in the coming years. These include increasing investment in renewable energy, improvements in energy storage technology, and efforts to expand access to electricity and clean cooking solutions in developing countries.
What can be done?
Build enabling infrastructure to facilitate energy access.
Increase investment in renewable energy: Governments and private investors can invest in renewable energy technologies like wind, solar, and hydropower. This could include subsidies, tax incentives, and other financial mechanisms to encourage the development and deployment of renewable energy technologies.
EXAMPLES: Solar energy: Solar energy is a renewable energy source that can be used to power homes, businesses, and other infrastructure. Solar panels can be installed on rooftops, or on the ground, and can be connected to the electricity grid or used in standalone systems in remote areas. Solar energy can be a cost-effective solution for providing electricity in areas with good solar resources.
Wind energy: Wind turbines can generate electricity by harnessing the power of wind. Wind turbines can be installed on land or offshore, and can provide a significant source of renewable energy. Wind energy is cost-competitive in many regions and can be used to supplement other renewable energy sources.
Hydropower: Hydropower generates electricity by harnessing the energy of moving water. Hydropower can be used in large-scale systems like dams or in smaller systems like micro-hydro turbines. Hydropower can be a reliable and cost-effective source of energy in regions with good access to water resources.
Bioenergy: Bioenergy involves using biomass sources like agricultural waste, wood, or other organic materials to generate energy. Bioenergy can be used in small-scale systems like cooking stoves or in larger systems like bioenergy power plants.
Geothermal energy: Geothermal energy involves harnessing the heat from the earth to generate electricity. Geothermal energy can be used in areas with good geothermal resources and can provide a reliable source of energy.
Energy storage: Energy storage solutions like batteries, pumped hydro storage, and thermal energy storage can be used to store renewable energy when it is available and release it when needed. Energy storage can help to ensure a reliable and stable supply of renewable energy.
