What is the cost of replacing the worldwide energy source with renewable energy?

Since "3.11", the way of energy policy has been increasingly questioned even in Japan, but the same can be said from around the world. Continue to increasePopulation of the worldAt the same time how to secure an energy source for,Renewable energyTransition to the future is one of the inescapable directions to realize a sustainable society. Infographic graphics that comprehensibly summarizes the cost of transition to such renewable energy is released.

The amount of energy consumed worldwide is equivalent to 8,777 million tons in terms of oil equivalent, and the amount of energy produced from it is 363 million TeraJouleIt will be a tremendous amount.


Converting this energy amount to another one corresponds to the energy of 2,795 hurricanes, the energy of the magnitude 9.0 class earthquake 877 times, but the average of hurricanes is 20.7 per year, and this class of earthquakes occurred in the past 1000 years It has not occurred.


Most of the current energy is produced from energy that is not renewable. The share of renewable energy is 16.1% surrounded by the circle on the bottom right.


The cost of this energy production is as follows. Global GDP (GDP), About 1.660 billion pounds (about 263 trillion yen), which is equivalent to about 1%, is spent on renewable energy sources.


However, it is said that this energy source is limited and exhausted around 2112. Also, in the course of creating energy, the earth is damaged.


The Arctic ice that was lost in about 30 years since 1980 is 4.39 million square kilometers, and its rate of decline has risen by 11.5% every 10 years. In Antarctica, since 2002, ice of 100 cubic kilometers each year has melted. As a result, the sea level increased by an average of 3.16 mm per year. The concentration of carbon dioxide, a greenhouse gas, was at most 300 ppm in 1950, up to 397.23 ppm in 2013. It continues to surge even now.


The use of non-renewable energy is not sustainable (sustainable). Moreover, continuing this will continue to damage the Earth.


So, how much equipment is needed to replace that energy source with renewable ones?

In a photovoltaic power generation panel, an area of ​​496 thousand square kilometers equivalent to the Spanish national land is necessary.


A windmill generator with a height of 100 meters and an output of 5 megawatts, that number is 8 million units.


For an output 750 kilowatt tidal power generator, 15 million units.


Output 7 Megawatts · With geothermal power generation equipment with power generation efficiency of 95%, 1 million points.


If it is a hydropower dam with output of 128,200 megawatts, 640 units are needed. By the way, the biggest power generation dam in Japan is in Nagano prefectureMinami-Aki DamIt is a pair of Ueno Dam and its power generation amount is 2820 MW.


The cost of replacing all of these is as follows.
·Solar power: About 20 trillion pounds (about 3,300 trillion yen)
·Wind-power generation: About 60 trillion pounds (about 9900 trillion yen)
·Tidal power generation: About 48 trillion pounds (about 7,600 trillion yen)
·Geothermal power generation: About 7 trillion pounds (about 1100 trillion yen)
·Hydro power generation: About 12 trillion pounds (about 1900 trillion yen)
Also, the average replacement cost for renewable energy will be about 30 trillion pounds (about 4,800 trillion yen).


About 30 trillion pounds (about 4,800 trillion yen) seems a tremendous amount, but it is 21% of the total GDP of 142 trillion pounds (about 2,500 billion yen) in the world.
