Every year, the world is using more and more energy. This massive scale of fossil fuel dependence pollutes the earth. On the other hand, we have abundant sun, water and wind, which are all renewable energy sources. So why don’t we exchange our fossil fuel dependence for an existence based only on renewables?
1. Do you think we need energy from other sources than those used so far?
2. Will people ever use only energy from renewable sources?
3. What can we do to contribute to the use of renewable energy?

I think that it is possible, that people will use energy only from renewable sources. But it will take time. First of all, people are more aware about enviorment, sources and their limits. No one wants to be surprised by dry source of energy, and renewable ones seem to be safe.
I think that best what we can do to contribute to use renewable energy sources is to educate - this is one thing that will spread itself and has got a constant impact. You can't take knowledge away.
Paulina, I’m glad you said about education. It seems to be essential to develop an environmentally sustainable world.
Andrzej, I feel that there have been huge advances made in architects’ awareness about eco-design and I’ve heard that they are, or they are supposed to be obliged by a kind of European laws which allows them only to create sustainable buildings. So as you said - there is a hope for us.
I don't think it's possible to exploit only reusable energy, but I really hope that someday reusable energy would become the main source of the power.
I think that the easiest thing we can do is to support fundations, laboratories or even governments which back up such initiatives.
I think that it is possible, that people will use energy only from renewable sources. World is developing very fast and it's only time when people find a way to get as many as possible energy from renewable sources.
What can we do to contribute to the use of renewable energy? I think that not too much. Maybe we should collect litters. We have a lot of engineers whose are thinking about that for us.
I think that we will see more use of earths core heat harvesting in the future but thats my speculation only. As for now Solar panels, Wind farms and Waterplants ftw.
Wind farm technology is expensive beyond normal pearsons reach and requires lots of investment beyond actual windmill. But what we can do not only to contribute but also to help ourselves is installign soloar panels on our roofs. With those we can reduce our electric bills and that investment when done right pays off in a longterm (about 2-3 year span)
Nowadays it's not possible even in Europe, not talking about the rest of the world. I think it can happen in 50 years at least.
First of all, we have to save the energy we use. Then, we have to buy less polythene packets etc. You know, there are a lot of ways of saving energy, because this issue is very topical.
I believe that we should constantly develop and look for new energy solutions. The constant growth in demand should also drive the development of new technologies. Renewables are a good direction, but I'm sure there are even better and more efficient solutions that I hope will be invented in the coming years.
I think we will but I believe it will neither be sun nor wind but completely new source. Not in our lifetime, though.
I think we should save as much energy as we can and try to use currently available renewable sources, for example by installing solar panels on our homes.
Yes I think we need energy from other sources than those used so far. In my dream world people draw energy only from the sun, wind and water. We don't need coal, oil or natural gas. I think in 30-40 years people will use only energy from renewable sources. Well we as units can do nothing. I think renewable energy is the next step in human development, and it will change naturally.
Nowadays, solar panels generate donations from EU, not power, as they are way too expensive to service, generate too little power and the batteries are too clanky and heavy.
If we won't change the financing and politics behind it, it will stick for a long time with being "ah, this ecogadget my neighbor installed in his yard, he paid $15000 for it, and even with 70% covered from EU funds, he doesn't use it, cause of the power plant deal that required him to re-buy his own energy".
On a local scale, there's actually a lot you can do. The solar panels keep getting cheaper, and the idea of creating self-sufficient building is gaining more and more traction. With the local advancements in creating see-through solar batteries (essentially windows that catch sunlight and turn it into electricity, that we could use for constructing all those glass covered sky-scrapers) and companies adapting to accommodate for local power production, we might get there sooner than we think.
Of course we have to save our enviroment as much we need to.
2. Will people ever use only energy from renewable sources?
It might be possible but we have to change many of our habbits and make renawable energy options cheaper.
3. What can we do to contribute to the use of renewable energy.
Make it more in common use - it will be cheaper then.
