The energy which is produced by solar panels you can sell only in the daytime. They have very low productivity and so during the night you will take out more energy than the sell day.

The advantage of PV is that it releases up to one order of magnitude less toxic materials (production, while in use and recycling).
Additionaly PV cost decreased by several magnitudes (70s: 70$ per kwh; 2015: 0.30$ per kwh) while c.o.p. increased by a factor of 5-8 ( 4-5% to now up to 25%. Special designs go up to 40%).

And the development is still ongoing and not finished. We will see much better stuff for less $ in the future.

Nope not unless it is on the taxpayer dollar and by that I mean subsidized cost an example being subsidizing the cost of changing a lightbulb although most green investments take years to recoup even with some rebates. Installing a new water heater unless your old one is really old is a good example even the solar panels unless you can sell back to the grid at a premium.

I'm not ready. But maybe you just need to reduce the cost of production of solar panels and batteries? I do not believe that it is not possible. Elon musk said that his tile which produces electricity from sunlight cheaper than usual. But if you can produce it in 3 countries it will be even cheaper.

In our current time, we, as consumers,  not ready to participate in that kind of sense because it is expensive but really helpful, not to mention the benefits for using it but it's not practical for us.

There is nothing wrong in supporting the renewables. But you must be ready to pay the price. For example, electricity from the thermal power plants cost around $0.03 per KWh. The same from solar panels cost at least $0.10 to $0.20 per KWh. Are you ready to pay the increased price?

I think there are a lot of videos that pertains to Life Hacks that can do those kinds of stuff, it is not just saving the environment by using recyclable materials, you get to save electricity that has an effect on the electricity market and it could lead to better stuff in the future. I hope everyone does it so at least we're doing something for our home, Earth.

Life without fossil fuel possible. Recently, it once again proved the Institute of electricity of Costa Rica (ICE), releasing a report, which stated that the country's electricity grid lasted 150 days on renewable energy. Half of these days occurred in the period from 16 June to 2 September. At this time, electricity was extracted with a variety of "green" energy sources.
According to the National center of energy control (CENCE), 80% of the electricity generated by hydropower, of 12.6% was generated by geothermal stations, and 7.6% have windmills and solar energy is brought only 0.01%.
And this is the second experiment in Costa Rica renewable energy. In 2015, the year the country endured them as much as 299 days. China, which is still jokingly referred to as "the world's factory", up to recent times has been the leader in the amount of emitted carbon dioxide into the atmosphere. But earlier the situation was the following: the growth of the economy and the percentage of carbon dioxide emissions were at the same level. Now China's economy is growing, but the volume of harmful emissions is not increased. The fact is that the country actively reduce the consumption of coal and invest in renewable energy. Last year, as reported by Bloomberg, the financial investment in this sector from China was 115 billion dollars, which exceeded the volume of investments in "green" energy in the U.S. and Europe combined.
Denmark, according to the official plan of the government, by 2050, should completely abandon the use of energy fuels. Now the country has about 40% of the energy obtained via wind. Denmark has a very long coast line, that allows the construction of many wind farms.

I'm a fan of cheap renewables. You can actually heat your house for free by building solar collectors yourself from scrap. There are many projects like that with the cheapest ones being built with just plastic water bottles and some tubing. If you manage to build panels yourself, you can save a lot of money each year and get instant ROI, because you won't have to put any money into the project.

Agree. Giving bonuses to using them would somehow make up for the expense of installing them. And with more people installing them, more would enter into the business to fulfill the demand. And more people in the industry means more innovation to see who can make the best for the cheapest price.

I'm a huge fan of renewables. Basically the technology is hear to go 100% green. What's really missing are big government incentives to speed up the process. That's something that really makes me sad.

In fact, a lot of methane. At the bottom of rivers, marshes, seas. It's silly not to use it. Can be to combat the greenhouse effect we need to protect our forests? Incentives for the production of electricity from solar panels will not help because traditional power is cheaper.

Government should give tax breaks for companies who use renewable energy. That might encourage them to actually use renewables as well as stimulate the renewables sector since there would be increased demand.

There has been several proposed projects in the past but I would like that at least someone focus on extracting energy from waste. Methane is a potent greenhouse gas and the less we pump out, the better. I don't know much about chemistry but I read that when burning methane, the byproducts would be just water and carbon dioxide. Sure, CO₂ is still a greenhouse gas and it's one that we're producing the most but it's still less potent than methane.

I remember Kaoshiung in Taiwan has converted an old dump site into a power plant (more reasons to segregate trash). Here in my 3rd world country, there are hog farms that collect the waste into a covered tank to produce methane, which they burn for electricity as well as for cooking.

Its a good way to start the massive used of the renewable energy in country side parts, put a solar panel in the roof of the great cities is a good start to in my opinion.

Now it has become very fashionable for private farms to build their own mini power plant based on solar panels and windmills. This makes it possible not only to provide yourself with electricity, and sell the leftovers to the state at a green tariff. Thus it makes it possible to earn on alternative energy and for the miner to have his energy.

All alternative energy sources are characterized by their low productivity and high price. Solar panels require constant maintenance linked to time of day and need to have expensive and long-lasting batteries.

Despite the fact that Japan is the most advanced country in the world in the sphere of high technologies, you have already realized that nuclear energy is very dangerous. Therefore, you need to try to use alternative sources Following the example of the sun, wind and high-speed rivers.

I think that solar energy is not yet very promising technology. Too little energy comes from solar panels. The cost of solar energy production higher than any other. I think that the future of nuclear energy. Although it's not the most environmentally friendly method of energy production. It can better improve the safety and disposal of nuclear waste than to figure out how to get an extra 1 kilowatt from solar panels?

Well that's true, we, as humans, we destroyed the planet due to the pollution we are doing and breaking the circle of life as we know it maybe by hunting, killing just for fun and other ways that you can destroy it. It's not that easy to replace species and it's starting to decline. I hope there's a way.
