How Much Energy Comes From Renewable Sources
How Much Energy Comes From Renewable Sources – As you may have heard, the world is warming, and in turn, people are trying to change their energy consumption to warm a little or slower. How’s it going?
A report released this month answers that question in detail. Published annually by the Renewable Energy Policy Network for the 21st Century (REN21, a think tank), the Global State of Renewable Energy Report (GSR) covers the growth of renewable energy sources, diverse energy sources, investment flows in clean energy and the progress of the country. for fixed purposes.
How Much Energy Comes From Renewable Sources
This is a knowledge base. Also… it’s really long. 250 pages long. Lots of words!
Building New Renewables Is Cheaper Than Burning Fossil Fuels
To save you precious time, modern consumers of information, I reviewed the report and found 12 charts and graphs that best illustrate the clean energy story in 2018.
First, we’re still going in the wrong direction. Global carbon emissions are not falling fast. In fact, they never fell; It increased by 1.7% in 2018.
Wrong way. Globally, fossil fuel subsidies increased by 11% between 2016 and 2017 to reach $300 billion per year.
Third, the cleaning effort is not difficult. This week brings good news for the United States — for the first time in April, more US electricity came from clean energy than coal in April, Bloomberg reported on Tuesday. But the GSR report shows that total investment in renewable energy (excluding hydro) was $288.9 billion in 2018 – the lowest for fossil fuels and an 11% drop from 2017.

All this is bad news. People seem to have the mentality that even when things go bad, they’re finally working for something good. This is not true. Together, we didn’t even manage to reverse course. Despite everything described below, we still had a hard time finding the emergency brake.
Let’s start with the good news: The growth of the energy sector cannot be stopped. Globally, more renewable energy was installed in four years of operation than both new fossil fuels and nuclear power combined. About 181 GW of new renewable energy was installed in 2018; currently produces more than a third of the world’s installed energy. These are conventional power supplies, they’re here to stay.
As you can see in the chart below, the addition of wind and bioenergy has been fixed; Hydropower has decreased a bit. The main reason why renewable energy is on the rise is the proliferation of solar photovoltaic (PV) panels.
55% (approximately 100 GW) of new renewable energy sources installed in 2018 were solar; Wind energy is 28%, electricity and water is 11%. The future of the earth really depends on the power of the sun to continue to grow.

The chart below also shows the growth of solar power in the USA, Japan (due to the Fukushima incident and nuclear accident) and more recently India.
In terms of power, China in general is large and numerous regardless of any group of countries. They were responsible for 32 percent of the world’s renewable energy in 2018. They are the world’s leading investor and leader in installed energy, hydro, solar and wind.
(Some points to note in the picture below: Japan’s solar and EU and US solar market share.)
Both growth and investment in renewables are starting to rise. Renewable energy accounts for one-third of the world’s installed capacity, and more than 26% of the world’s electricity is produced, as shown in the figure below.
How Does Your State Make Electricity?
However, hydropower accounts for more than half of renewable energy, about 16%. What people like to think of as renewable energy, wind and solar is only 8%. Even in the electricity sector, renewable energy still has a long way to go.
Innovative political economy: Solar energy creates many jobs. Although renewable resources are scarce, they make up the bulk of the world’s renewable energy services. The wind that leads to solar energy is very active. Solar PV is complex.
Good news is hard to find outside of electricity. Renewable energy sources account for 26% of global electricity, just under 10% (less than 2% renewable) for heating and cooling and 3.3% (only 0.3% renewable) for traffic energy. forming.
Heating and cooling, which accounts for 51% of the world’s energy use, is largely due to natural gas and oil. Transportation, which accounts for 32% of the world’s energy use, mainly uses gasoline and diesel.
Renewable Energy On The Rise: 37% Of Eu’s Electricity
There are 169 countries that exceed national or state/provincial renewable energy targets. Meanwhile, the report said, “Only 47 countries have heating and cooling targets, while the number of countries with legislation has dropped from 21 to 20.” While less than a third of the world’s total countries have building codes, “60% of the energy used in buildings in 2018 occurred in regions without an energy use policy.” Approximately one third of the industrial energy used in industry is affected by industrial energy efficiency policies.
Not better for transport, where “light vehicle policies were implemented in 40 countries at the end of the year and largely phased out by heavy vehicles”.
The carbon price doesn’t help much either. “The price of carbon is underutilized,” the report said. “As of the end of 2018, only 44 states, 21 territories and 7 cities have implemented carbon pricing policies, accounting for only 13% of global CO2 emissions.”
Here’s the news in the US and around the world: More energy is starting to consume electricity, but it’s slowing everywhere else.
Renewable Energy Saves Water And Creates Jobs
Even though transportation still runs on fossil fuels, change continues. In 2018, “the number of electric vehicles worldwide increased by 63% compared to 2017” and “many cities are switching to electric buses,” the report said.
China is once again outpacing the rest of the world, even as its aggressive electric vehicle policies shout at the tiny country of Norway, which reflects global statistics.
The report has a special report on the growth of clean energy in cities around the world. On average, cities that account for 65% of the world’s energy consumption and are home to more than half of the world’s population use more electricity than countries. Currently, there are about 100 cities around the world that use between 90% and 100% renewable electricity. At least 230 have installed 100% renewable energy in one region.
G20 countries meet annually to denounce fossil fuel subsidies and promise to bring them back. And every year, fossil fuel subsidies increased by 11% to $300 billion in 2017. “Although at least 40 countries have made changes to fossil fuels since 2015,” the report states, “fossil fuel subsidies still exist. At least 112 in 2017, when at least 73 countries gave more than $100 million to each.

And this is live support. As my colleague Umair Irfan points out, a recent IMF article estimates that the total cost of fossil fuels – both direct, taxes and financial transfers, and indirectly, the market has no value in terms of damage to the environment – is up to $5.2 trillion. . in 2017.
Any climate model that involves humans reaching the carbon target involves a rapid decline in “energy intensity,” that is, the amount of energy used to produce a billion dollars. It is important in GDP. Theoretically, if you can quickly reduce energy consumption, you can overcome the increase in natural energy consumption (due to population and economic growth) and reduce overall energy consumption.
In theory, anyway. In fact, the world’s energy consumption has decreased by 2.2% over the past five years. This is not enough to offset the 1.2% increase in global energy consumption.
Electricity is decreasing at a rate of about 0.4% per year. To meet the world’s goals by the middle of the century, the world’s energy needs to decrease by 4 to 10 percent per year. That means the world needs to speed up electricity by about 10 times.
Fossil Fuels Still Dominate U.s. Energy, But Renewables Growing Fast
So what does all this involve? One (imperfect) way to measure renewable energy progress is to measure them against final energy consumption (TFEC), which adds to the total energy used worldwide.
As of 2017, fossil fuels still provide about 80% of human energy, and that’s what they’ve been providing for decades. Traditional ecosystems aside, with all their challenges of felling trees, growing monocultures, and striving to eat on land, you’ll be left with only about 13% of climate-friendly energy (Different people may want to leave some areas, but the main point is).
That 13 percent needs to reach or close to 100 percent by 2050 – so you’ll only notice 30 years from now. Thirty years ago, I was 17, listening to cool music and drinking at barn parties. It doesn’t look like that for a long time.
