In contrast, controllable renewable energy sources include dammed hydroelectricity, bioenergy, or geothermal power. Percentages of various types of sources in the top renewable energy-producing countries across each geographical region in 2023. Renewable energy systems have rapidly become more efficient and cheaper over the past 30 years. [3]
Fossil fuel phase-out is the gradual reduction of the use and production of fossil fuels to zero, to reduce air pollution, limit climate change, and strengthen energy independence. It is part of the ongoing renewable energy transition, but is being hindered by fossil fuel subsidies.
Energy storage helps overcome barriers to intermittent renewable energy and is an important aspect of a sustainable energy system. [154] The most commonly used and available storage method is pumped-storage hydroelectricity , which requires locations with large differences in height and access to water. [ 154 ]
In 2009, President Barack Obama in the inaugural address called for the expanded use of renewable energy to meet the twin challenges of energy security and climate change. Those were the first references ever to the nation's energy use, to renewable resources, and to climate change in an inauguration speech of a United States president.

Solarpunk may take practical inspiration from Earthships, which are an example of sustainable architecture. [1] [2]Solarpunk is a literary and artistic movement, close to the hopepunk movement, [3] that envisions and works toward actualizing a sustainable future interconnected with nature and community.
The second target of SDG 7 is Target 7.2: "By 2030, increase substantially the share of renewable energy in the global energy mix." [8] It has only one indicator: Indicator 7.2.1 is the "Renewable energy share in the total final energy consumption". Data from 2016 showed that the share of renewable energy compared to total energy consumption ...
