It doesn't take much. It is enough that only 1% of the territory of a state is dedicated to photovoltaics to satisfy 100% of the energy demand

Photovoltaic. Solar energy can cover the entire needs of a state with just 1% of its land coverage. In practice, it is enough that only the1% of the territory of a state is intended for photovoltaics for meet 100% of its energy demand. Only a small part dedicated to photovoltaic modules to free themselves from the slavery of oil and fossil fuels. This was revealed by the WWF which today presented a dossier at the World Future Energy Summit in Abu Dhabi.
The document, entitled Solar PV Atlas: solar power in harmony with nature, shows through seven cases, is based on simulations of six different countries and a regional area with different sun exposure, and has shown that they are not needed large portions of land, but only 1% to cover a nation's electricity needs.
The dossier hypothesized this possible solution in seven countries, far from each other by geographic location but also at a demographic, economic and political level. They range from Indonesia to Madagascar, up to Mexico and Morocco, South Africa, Turkey and the Indian region of Madhya Pradesh. For each of them, the land consumption was calculated to produce 100% of the energy from the sun.
Contrary toopinion widespread and shared, endless expanses of land are not needed to produce enough energy, but a quantity that the WWF defines as “negligible” is enough. According to the report, in fact, in these seven areas of the Earth it would take just under 1% of the surface to meet 100% of the electricity demand needed in 2050, considering only the electricity produced with photovoltaics, and without including any other forms of energy production.
“Research has found that the photovoltaic power plants they can provide significant environmental benefits, including low environmental impact and clean energy in a short time. Replacing the existing power grid with photovoltaic panels would significantly reduce greenhouse gas and heavy metal emissions, as well as water use, ”explained Solar Vice President Lettemieke Mulder.
This new WWF report therefore supports the view of the 100% renewable by 2050: “We are actively promoting investments and measures towards renewable energy technologies that help make this happen,” added Jean-Philippe Denruyter, Head of WWF's Global Renewable Energy Policy.
The report shows that the photovoltaic technology, if well planned, does not conflict with the conservation and protection objectives of the territory.
