As the world warms, the number of households without electricity is expected to double, from about 9.5 million in 2020 to about 12 million in 2060.
But what will become of the homes that remain?
Some of these are in the most vulnerable regions, particularly in countries like the US and Russia.
“We have to think of the long-term future,” says Svetlana Kuznetsova, chief executive of the Russian Solar Energy Corporation (Rosenergoatom), a state-owned company that owns and operates more than half of the world’s solar installations.
“We have a lot of work to do in that direction, to make sure that the future of our people, of our energy supply, is protected.”
The problem is that, unlike other sectors of the economy, like manufacturing, it’s not clear what sort of technology will be available to create new jobs in the years ahead.
So what is the future looking like?
The International Energy Agency predicts that solar will generate enough electricity to power roughly 20% of all new global demand in the next 50 years.
That’s good news for those who live in those countries.
But in the United States, solar is likely to fall far short of that projection, as the country’s solar sector is currently in a slump.
A lot of this will depend on how fast the country becomes more energy independent, and how rapidly it moves towards a low-carbon economy.
Solar, however, is a rapidly evolving technology.
There are two main types of solar panels.
Some panels can produce electricity using solar energy, and some can produce energy using wind.
But the technology to make solar panels from silicon or carbon fibre is still far from being commercially viable.
One of the biggest problems facing the solar industry is that silicon and carbon are both expensive to produce, and their prices are falling.
However, silicon has the advantage of being a very efficient material, and carbon fibre has a lower melting point than silicon, meaning it can be used more cheaply than silicon panels.
The industry is also struggling to find cheaper and better ways of making panels, as it is still recovering from the 2008-2009 financial crisis.
In the meantime, solar energy is still a relatively new industry, and there’s no obvious technology to build it into a new generation of large-scale, affordable solar energy systems.
The US Solar Energy Industries Association (SEIA) has put forward a plan to build solar energy into a range of small, cheap homes.
And there are several promising projects underway in Russia, where Rosenergoat is building the countrys largest solar energy plant.
Although the US government has recently been investing in renewable energy, there are some signs that the US solar industry may be slowing down.
This is because US solar energy companies have been competing with Chinese and Japanese firms to produce panels.
And there is no guarantee that China and Japan will make the same investments in the US, even as they both have a huge presence in the solar sector.
According to the International Energy Association, China’s solar market is expected grow to US$1.1 trillion by 2035, while Japan is expected get a similar growth to US $7.4 trillion.
By 2050, according to the World Bank, the US will overtake Germany as the worlds largest energy consumer, after Japan.
All of this is not to say that the world of solar is yet to enter the future.
While solar is becoming more affordable, the world still needs to be very careful.
Because the US has the largest installed capacity in the world, it is also one of the largest users of fossil fuels.
For example, coal-fired power plants are still used by about 70% of the country, while solar panels generate about half of all energy.
Furthermore, as a nation, the United Kingdom is the largest consumer of coal in the entire world.
With a new energy policy, the UK may be able to start to cut its carbon footprint, but the world may not.
Despite the economic difficulties faced by the solar energy sector, solar power is likely going to be a major part of the future for a lot longer than it looks right now.
