Where is Solar Energy used?

Map of the world

This is where Solar Energy is used most in the World

While the sun is a continuous and powerful source of energy, the question is where is solar energy used here on earth? Solar cells and solar panels allow us to harness that energy, offering renewable methods of generating electricity. The opportunities solar power presents has made it the third most important renewable energy source in terms of globally installed capacity, after hydro and wind.

However, some countries have taken advantage of this technology more than others. But where is solar energy used most? This handy guide will reveal which countries use solar power the most and why, so that hopefully we can learn from their actions.

Which countries have the highest installed solar power capacity?

Why is China Number one in the world?

Map of the world focussing on China

When you consider how large the Chinese solar power industry is, it makes sense that China has the highest installed solar power capacity in the world. Solar power is one of the biggest industries in mainland China, and globally China is the world's largest market for both photovoltaics and solar energy. China has been the primary installer of solar photovoltaics, which absorb the sun's light to create electricity, in the world since 2013, with over 400 solar PV companies in China. In 2015 China reached a photovoltaic installed capacity of 43 GW, setting it on track to be the world's largest producer of photovoltaic power. China also dominate the market for solar heating, achieving a total installed capacity of 290 GW by the end of 2014, 70% of the world's total installed solar thermal capacity.

China shows no signs of slowing down in their quest for solar power supremacy, as evidenced by its consistent increase of its annual and short-term targets. China has set itself an ambitious target of installing 150 GW of solar power by 2020. Its solar capacity target for 2017 is 70GW.

Germany in second place

Map of the world focussing on Germany

Like China, Germany's success in the solar power market is helped by setting ambitious but achievable goals. The government have set a target to reach a 35% share of renewable electricity in the country, which Germany is on target to achieve, with the current share being around 31%. Other long term minimum targets include a 50% share by 2030 and 80% by 2050. More and more, Germany is producing more electricity than it requires, driving down spot-market prices and exporting the extra electricity to neighbouring countries.

Germany is not far behind China, whose solar power consists almost entirely of photovoltaics. Germany was the world leader of photovoltaic capacity since 2005, with a total installed capacity that added up to 40,490 megawatts by the end of September 2016. Photovoltaics are responsible for 6% of Germany's energy demands.

You wouldn't think that Germany has the second highest installed solar power capacity, especially when it's nowhere near the sunniest country in the world. But the substantial growth of solar power is largely due to Germany's feed-in tariffs for renewable energy, which were introduced by the German Renewable Energy Sources Act. Since 2006, prices have decreased by more than 50% in five years.

And in third place - Japan

Map of the world focussing on Japan

As the fourth largest energy consumer in the world, solar power is very important to Japan. The 2011 disaster at Fukushima has also nudged policy towards renewable energy. Since the late 1990’s, Japan's solar power capabilities have been increasing. It has long been a major photovoltaics (PV) manufacturer and is in the top five countries with the most domestic PV systems installed, with 4,914 MW installed by the end of 2011, with most of it grid connected.

With financial incentives such as feed-in tariff schemes, Germany can be seen as the country where solar energy is used the most. Emulating Germany’s actions and goals, the rest of the world can also benefit in their own development of solar power capacities.

Solar Energy vs Coal: A Comprehensive Comparison

solar energy vs coal

How does solar energy stack up vs coal for electricity generation?

In 2015, the United States used about 3,724,500 million kWh of electricity.

Most of us don’t have enough context to realize how big this number actually is, so here are some facts: First off, the US is the 2nd biggest user of electricity in the world (just behind Canada). Secondly, think about what exactly this number includes: all the electricity used in millions of homes across the US for air conditioning, lights, refrigerators, stoves, hot water, and all our devices, as well as factories, office buildings, data centers, agricultural applications, government offices, recreation centers, football fields, streetlights, and about a billion other things we don’t even think about on a daily basis.

With so much electricity being used and created every day, as a country we need to constantly assess if all this electricity is being created in the most responsible way, both monetarily and environmentally.Continue reading

Why Climate Denier WattsUpWithThat Went Solar

climate denier

How – and more importantly why – some blogger has decided to go solar might not be of great interest, after all, lots of people have gone solar now. But this is not just any blogger.

Anthony Watt’s blog WattsUpWithThat is one of the most influential sources for climate denial hysteria out there.

The WattsUpWithThat argument against climate change tends to be of the “oh, the hypocrisy” variety of climate change denial. You know the kind of thing: “Fat Al Gore flies in airplanes; so climate change is a hoax.”

Apple Energy: Some strange solar news from Apple has the rumor mill abuzz

On June 6, Apple’s new, fully owned subsidiary Apple Energy filed an application with the Federal Energy Regulatory Commission (FERC), for a permit to sell solar electricity and flexible grid services on the open electricity markets all over the USA – starting August 6.

Utility-Owned Solar: Averting the “death spiral”?

A war has been declared between the upstart solar industry and the older electricity suppliers.

The war is essentially between centralized and distributed energy. The electric utilities were originally set up in the days of large-scale centralized coal power stations and regulated as suppliers of essential public services.

Stop Arguing Carbon Tax VS Cap-and-Trade: Mandates Work!

Ten years ago, I would not have said this, because I was convinced that it would be cap-and-trade that would switch us to a renewable future.

I was one of those arguing with reluctant Democrats who were convinced that cap-and-trade was “just a giveaway to polluters” and of course Republicans sneered that carbon taxes were “the equivalent of the medieval “penance.”

How Decoupled Utilities Could End the Solar-Utility War

decoupled utilities

When the Obama administration began in 2009, there were only five states with decoupled utilities. Now there’s sixteen.

Decoupling a utility’s revenue from its total sales is intended to solve a “perverse incentive” that reduces utility motivation to increase energy efficiency.

As part of the American Recovery and Investment Act in 2009, states were invited to compete for $3 billion in Energy Efficiency Program funds to encourage utilities to incentivize reduction in electricity demand. Governors had to verify to the DOE that the state’s Public Utility Commission (PUC) would decouple the utilities’ revenue from profits.

Photovoltaic Effect: A historical overview

photovoltaic effect

The photovoltaic effect turns light into electricity, instantly, as if by magic. There is no machinery, no power block, no turbines, unlike all other techniques for creating electricity.

This magic happens within a sheet of material that looks to the naked eye just as inert as any other material object.
