On Tuesday 12th March, some of the classes had a lecture called Energy - the future of mankind which dealt with getting, working with and future using of energy. Both lecturers introduced themselves - Ing. Ondrej Trubka and Tomas Heil – sort of strange but very funny, and the lecture could start.

Firstly, we were reminded of New York blackout several years back where we realized the importance of energy and shortly within only the second slide we could understand how essential the topic of the presentation is.  We were shocked having been told that there are more than a million of people still living without electricity and the rise of the population is much faster than the efficient supply of electricity. It's also very significant that 20 % of people use 80 % of energy.

The solution could be seen in electro cars or batteries. However, nobody has come with the solution to a crucial question: How to store energy, which is the whole issue of energetic industry. We can hope that our lecturers have brought the problem and some of our student might solve this issue.

More of repetition was the part where we learn about getting energy (nuclear power stations…). Nevertheless, the topic was presented in a very interesting way and still, there were some new pieces of information.  We were thinking about renewable and non-renewable resources and we could realise what it brings to get energy.

Some extra information came with medialized disasters where only a few people died while those when much more people died, hundreds even, have not been spoken at all. It sort of put more into an issue of teens nowadays: misinformation on the Internet.

We were really impressed by extra activity were we were shown radioactivity of some subjects. It was funny. Moreover, we could see radioactivity around us, everywhere, which is something that most of us haven't know before. The experiment was completed with a photo competition with interesting prices. Honestly, nobody participated. We might have been afraid to get embarrassed not coming with anything interesting about energy or being ashamed because of our pictures.

At the end we were talking about coming changes in energy topics, advantages and disadvantages of energetic industry and various risks such as emissions, litter of high prices.

The whole lecture was very enriching and greatly spent time from the point of view on new gotten facts and our thinking about the future. I hope we have more of these lectures and I would like to participate.
