You may have heard of the term ‘100% renewable energy’ in reference to towns, cities and countries.
In this guide, we discuss what is it, what current progress is, and whether it’s possible by 2030 and 2050.
Summary – 100% Renewable Energy
100% renewable energy is supplying 100% of energy by renewable energy sources, specifically by modern renewable energy sources like solar and wind.
Some cities and countries already have a majority or full renewable energy mix in their electricity supply, so, 100% renewable energy is possible
Countries and cities that aren’t 100% renewable energy supplied in their electricity sector may have different plans for achieving 100% renewable energy by 2030 or 2050 (or another year that they have identified as their target year).
Plans for 100% renewable energy differs by each country and city, and can depend on many variables and factors.
The support of the government and government policy is a huge variable
There are models and studies that have been put together that can forecast the feasibility of different energy mixes for different cities and countries (these forecasts are obviously estimates).
There’s also websites that provide updates on the cities worldwide that are taking action on different sustainability measures in real time
It should be noted that some cities and countries may determine that 100% renewable energy isn’t ideal for them individually.
A hybrid mix including fossil fuels and nuclear power may be ideal for different reasons
What Is 100% Renewable Energy?
100% renewable energy is supplying 100% of energy by renewable energy sources, specifically by modern renewable energy sources like solar and wind (but can also include other renewable energy sources like hydropower, geothermal, tidal and wave energy, and so on).
Right now, it primarily refers to 100% renewable energy supply in the electricity sector.
But, in the future, it could also refer to 100% renewable energy supply in other sectors that are currently fossil fuel dominated, like transport, and heating and cooling.
Is 100% Renewable Energy Actually Possible?
Yes, some cities and countries already run on 100% renewable energy.
But, each country and city faces different challenges and problems with transitioning to a majority or full renewable energy supplied mix.
100% Renewable Energy Countries & Cities
According to wikipedia.org, the number of countries getting at least 90% of their electricity from renewable energy sources was 12 countries
The countries currently getting 100% of their electricity from renewable energy sources are:
Albania – 100%
Democratic Republic Of The Congo – 100%
Iceland – 100%
Paraguay – 100%
As of January 2018, 42 cities were getting at least 100% of their electricity from renewable energy sources, 59 cities were at at least 70%, and 22 cities at at least 50% (according to CDP.net’s interactive map)
100% Renewable Energy By 2030, & 2050
Studies & Reports Of The Future
Some studies and reports analyse factors like the year a city or country can reach 100% renewable energy, the challenges in getting there, what the energy mix might look like, and more.
Real Time Progress
Some websites provide information on the real time progress of some cities worldwide meeting certain sustainability measures.
Plans For 100% Renewable Energy
Each city and country has different plans for transitioning to an increased renewable energy mix.
Government support is a big variable.
Some national and State governments are more pro renewable energy than others, for different reasons.
