SDG 7 - SDG 7

Affordable and Clean Energy

SDG 7 is Affordable and Clean Energy, but what does that really mean? SDG 7 has five targets that it has to reach to be achieved by 2030, and those goals add up to ensuring access to affordable reliable sustainable and modern energy for everyone globally. This means that to achieve SDG 7, everyone has to have access to a cheap energy source - affordable - and an efficient energy source - clean - that doesn't hurt the environment. The best way to do that is with renewable energy!

Renewable Energy

According to the International Energy Agency (IEA), about 28% of the world's electricity generated comes from renewable sources. This is definitely a start, but we need to increase that number if we want to get to net zero emissions by 2030 and achieve SDG 7. There are many ways to use renewable energy, and many renewable sources. Some examples include solar power, wind power, hydropower, and geothermal power, which can be used to power things like lights in your house or keep your water supply going. By using renewable energy resources, we can lower the amount of carbon that goes into the atmosphere and help stop climate change in the process.

How It Works

Here's how renewable energy works. First a renewable energy source like a solar panel or wind turbine is installed. Then, the renewable source compatible with the source, like a sun with solar panels, takes place. Then for example, the sun would hit the solar panels and a complicated energy transfer occurs. The energy will then have changed from thermal energy to electrical energy. The grid can now use this energy as electricity and it will be used to power houses.

Clean Cooking

SDG 7 doesn't only mean getting energy to your house. An important part of Affordable and Clean Energy falls under clean cooking. Clean cooking can be broken up into two parts.

Making sure that food that is being cooked by people worldwide is healthy for them to eat (clean cooking tech.)
Making sure that the fuels used to power cooking technology is clean for the environment (no carbon dioxide)

The first part of this is to ensure the safety of people eating food cooked on bad cooking appliances. This means that if someone is using a old rusted pan to make food or using old methods like burning a pot over a fire, that the people eating the food can stay healthy. We need to replace bad cooking technology with newer things so people can stay healthy.

The second part means that the technology being used is good for the environment. This means to use modern cooking appliances instead of cooking something over a fire, which would release carbon dioxide into the air. Around 34% of man-made greenhouse gases come from food systems, and that number needs to be lowered. The greenhouse gases can be produced by facilities that make the food and also when you cook the food at home with unclean cooking appliances.

Targets

SDG 7 has five targets.

Target 7.1 - By 2030, ensure universal access to affordable, reliable and modern energy services.

Target 7.2 - By 2030, increase substantially the share of renewable energy in the global energy mix.

Target 7.3 - By 2030, double the global rate of improvement in energy efficiency.

Target 7.a - By 2030, enhance international cooperation to facilitate access to clean energy research and technology, including renewable energy, energy efficiency and advanced and cleaner fossil-fuel technology, and promote investment in energy infrastructure and clean energy technology.

Target 7.b - By 2030, expand infrastructure and upgrade technology for supplying modern and sustainable energy services for all in developing countries, in particular least developed countries, small island developing States, and land-locked developing countries, in accordance with their respective programmes of support.
