Are wind and solar power the answer to our energy needs? There’s a lot of sun and a lot of wind. They’re free. They’re clean. No CO2 emissions. So, what’s the problem?

Why do solar and wind combined provide less than 2% of the world’s energy?

To answer these questions, we need to understand what makes energy, or anything else for that matter, cheap and plentiful.

For something to be cheap and plentiful, every part of the process to produce it, including every input that goes into it, must be cheap and plentiful.

Yes, the sun is free. Yes, wind is free. But the process of turning sunlight and wind into useable energy on a mass scale is far from free. In fact, compared to the other sources of energy — fossil fuels, nuclear power, and hydroelectric power, solar and wind power are very expensive.

The basic problem is that sunlight and wind as energy sources are both weak (the more technical term is dilute) and unreliable (the more technical term is intermittent). It takes a lot of resources to collect and concentrate them, and even more resources to make them available on-demand. These are called the diluteness problem and the intermittency problem.

The diluteness problem is that, unlike coal or oil, the sun and the wind don’t deliver concentrated energy — which means you need a lot of additional materials to produce a unit of energy.

For solar power, such materials can include highly purified silicon, phosphorus, boron, and a dozen other complex compounds like titanium dioxide. All these materials have to be mined, refined and/or manufactured in order to make solar panels. Those industrial processes take a lot of energy.

For wind, needed materials include high-performance compounds for turbine blades and the rare-earth metal neodymium for lightweight, specialty magnets, as well as the steel and concrete necessary to build structures — thousands of them — as tall as skyscrapers.

And as big a problem as diluteness is, it’s nothing compared to the intermittency problem. This isn’t exactly a news flash, but the sun doesn’t shine all the time. And the wind doesn’t blow all the time. The only way for solar and wind to be truly useful would be if we could store them so that they would be available when we needed them. You can store oil in a tank. Where do you store solar or wind energy? No such mass-storage system exists. Which is why, in the entire world, there is not one real or proposed independent, freestanding solar or wind power plant. All of them require backup. And guess what the go-to back-up is: fossil fuel.

Here’s what solar and wind electricity look like in Germany, which is the world’s leader in “renewables”. The word erratic leaps to mind. Wind is constantly varying, sometimes disappearing completely. And solar produces little in the winter months when Germany most needs energy.

GREEN ENERGY IN CHINA



Views:245668|Rating:3.41|View Time:4:48Minutes|Likes:77|Dislikes:36
On average, Chinese people use a third of the energy used by a person in a developed nation, yet China is one of the world’s largest emitters of greenhouse gases. So how will China fulfil the responsibilities agreed in the UN Paris Agreement (CMA1)?

Let’s take a look at how China plans to reduce its energy consumption, introduce new technologies and the different energy sources used – hydropower, wind power, solar power, geothermal energy and nuclear power.

China’s goal is that 20% of its energy will come from non-fossil fuel energy by 2030. So where will it come from?

China not only possesses the largest installed hydropower capacity in the world, but also the most advanced hydropower technology.

China’s wind power industry is the fastest growing in the world with two wind turbines installed per hour in 2015. China’s biggest plant has more than 3,500 turbines. But next, China needs to improve the grid to make sure it can use all the wind power that it generates.

China can make more solar energy than anywhere else on earth and also supports the development of solar power worldwide with advanced technology and equipment. In 2020, the country’s solar panel installation capacity will reach 110 million kilowatts – which can provide electricity for 80 million people.

It is particularly valuable in rural provinces, where more and more people are turning to home solar systems for energy.

Turning agricultural residue into pellets has kick-started a national biogas industry in China.

120 kilometres south of Beijing, China has developed its first smoke-free city – Xiong County, which has become a model for other parts of China. 95% of its heating comes from geothermal sources.

As China has one sixth of the world’s geothermal resources, this resource will help to increase China’s use of non-fossil fuel energy from 12% to 15%.

Nuclear power currently accounts for 3% of China’s total power generation. China’s nuclear power units in operation have never had accidents at or above Level 2 on the International Nuclear Accident Classification scale.

But China’s plans to reduce carbon emissions don’t just focus on clean energy – it plans to reduce its energy consumption and introduce new technology and approaches.

China has become the world’s largest electric and hybrid vehicle market and is subsidizing the industry to make it more attractive for manufacturers and consumers. And in 2017, China introduced the world’s largest carbon-trading market encouraging companies to curb emissions.
