1) http://www.youtube.com/watch?v=V9SrAGvhBbU

the reason I find this video useful is that
energysaving is becoming
increasingly important. I believe, in the near future it will become
unaffordable for an average person to live in a non-passive house or
build a new house not meeting passive energy standards. That is due to the
rising energy costs. And because of the pressure of public opinion and
changes in govermental legislation. Therefore it would be useful to
start embracing the concept already today, for it's useful for one's
budget anyway, as well as to the environment.

2) http://www.ted.com/talks/avi_reichental_what_s_next_in_3d_printing.

The video is about 3D printing and how it is changing production
possibilities that have emerged since the industrial revolution. As a
common factory today produces personal goods that are modelled as "one
fits all", the 3D-printing production will change it to more individual
approach - e.g sunglasses that fit perfectly. With 3D printing the
objects can be most complex and it won't affect time or cost of the
production. The materials used on 3D printing can be almost anything
solid, including food, plastic, stone and metals.

3) I have chosen this video because i think the space energy, solar, is the 

future. At the moment i'm involved in the field of photovoltaic solar
panel solutions for home and businesses, under 100 Kw. The video was
interesting and i think i have found a good subject.

4) I have several favourite videos about energy topic. The one i chose to send is here : https://www.youtube.com/watch?v=Gz_L6KuqvFI

It's called "The future of energy?". This video is interesting, because it talks about cutting CO2 emission, what is really big problem in our society nowadays. We are emitting so much CO2 into the atmosphere that it could cause climate change. In this video three academics are talking about opportunities of how to cut back on C02 emissions. This is also quite informative, because it's made by Cambridge University. I hope that you will enjoy also this video.

5) http://www.youtube.com/watch?v=2pWfYgBR3Ro

I chose this link 'cos i installed that kind of systems myself, although this system includes solar panels as well. 

this video helps you understand how a solid fuel boiler works, and what you can add for that kind of systems.

solid fuel boilers, inside plumbing work, an interior installation, is my extra work for extra money. My everyday work for living is object manager and we install outside plumbing, water systems, reservoirs for the drinking water and waste water. the list is long .

I find it interesting and you can stay modern with energy - that's why i decided to come and study.

6) I've found some materials from the internet to make some practice. The 

Youtube link will be added below:
https://www.youtube.com/watch?v=rO5rUqeCFY4
The theme is very interesting. Actually it's the first time I have heard about
this kind of solar reflection system usage in energy producing and
therefore I thought, maybe its interesting for other students from our
group too! Anyway, its quite interesting and quite easy to get the point
of the system. Unfortunately that method of powering wouldn't be that
effective at latitudes where Estonia is located, because of
Sun-deficiency.

7) http://www.youtube.com/watch?v=rXepkIWPhFQ

  This video is about Lifesaver water bottle.
We know that some continents and countries need clean drinking water. And
after a natural disaster in Asia and the hurricane Katrina. Michael
Pritchard invented the Lifesaver bottle. Lifesaver pores are 15 nanometres,
the smallest virus is about 25 nanometers. So nothing is getting
through. It'll last for 6,000 liters. It is a very practical and compact
system, which will help to save many lives.

Alternative energy
I got to know, what algae, viruses and seawater have in common. They all
put fossil fuels out of business.
The fact is that the USA goes through 19 mln barrels of oil every day
not thinking that coal and oil won't last forever.
Even germs can make electricity. Scientists discovered 2012 that by
coating electrodes with germs that have this piesoelectric
effect, they can generate electricity through compression.
It's good to know that brilliant people all over the world are figuring
out the ways how to create energy from everything,
from germs to garbage.

9) GOOD AND HIDDEN SIDES OF WIND POWER

We encounter electricity on a daily basis in modern life- its necessary for light, operating machinery,in households, industry, transportation etc.

Energy is produced from fossil fuels, nuclear fuels, hydro energy, also from renewable energy sources.

Increasing pollution and environmental problems, also diminishing natural resources have created necessity to pay more attention towards using renewable energies. One possibility is to create renewable electricity from wind.

Wind energy gets more attention as a field of industry, which enables us to use wind to produce electricity. No other energy sources other than wind are used to create wind electricity. Wind is a renewable resource and therefore environmentally sustainable (not to take into account producing costs for generators).

However, this growing industry has both supporters and opponents. And both sides have their arguments, proof, theories and lobbyists There are large sums of money and subsidies circling in wind power industry, costs of which will be paid by taxpayers.

 The first link https://www.youtube.com/watch?v=8btlmWn0xdY presents statements and examples of wind energy usefulness. A 3,2MW wind generator has been taken as an example. However, I have a sceptical attitude towards some calculations: 

• wind energy is one of the most efficient renewable energy sources;
• high efficiency in presence of sufficient wind;
• long service time (25 years);
• saving up to 2365 tons of CO2 atmospheric waste yearly;
• modern wind generators are quiet. 

The second link https://www.youtube.com/watch?v=WJgYZfX4lLc presents problems and human opposition to wind energy: 

The indicators used are:

• worsening of living environment;
• noise and vibrations, which disturb people and animals;
• benefit mostly owners of wind parks, their profits are paid by end-users;
• no „green“ energy is entirely green – you need raw materials and energy to produce generators;
• not so long lifetime of generators (25 years).

Although these two paragraphs were taken as examples from foreign wind parks, there are many same kind of problems in Estonian wind parks.

Largest opposition is due to harsh decline in human and fauna life environments. Consumers also oppose inappropriately large wind park owner’s profit margins.

European Commission points out, that in early years renewable energy needed subsidies to survive on renewable energies markets, but situation has changed drastically by now – development of technology has made renewable electricity much cheaper. Many countries, including Estonia, have started reforming renewable energies subsidies. Below are some main points from EC communiqué:

§  financial subsidies should be clearly required-only basis and help competitiveness of renewable energies;

§  support schemes should be flexible and take into account falling energy producing costs. The ultimate goal should be ending subsidies and switching to market prices. It means that permanent discount tariffs should be replaced by principles, which are directly tied to market prices and would create motivation for market participants to answer market expectations.

For example, it has been agreed on German coalition negotiations to slow down erecting new wind generators in both mainland and marital wind parks, to contain sharp rise of electricity price, due to renewable energies fees. The goal in marital wind parks is 6,5GW instead of 10GW by the end of decade, the original goal of 25GW has been reduced to 15GW by year 2030.

The council of German energy experts has recommended reforming thoroughly the whole energy sector, not just renewable energies. The council recommended to freeze the German law regarding renewable energy subsidies until fundamental plan to reform the whole system has been developed. Experts noted that to achieve success in renewable energy subsidies, there has to be a solution that encompasses the whole Europe and suggested to strengthen EU waste trading system, which should become main instrument in European climate policy.

I think excessive subsidising of (wind)energy in Estonia will decrease in the future and other alternative energies will be considered. One thing is sure though – wind energy will not disappear in near future. 

10) The future of energy?

https://www.youtube.com/watch?v=Gz_L6KuqvFI

I liked this video because it brings out positive and negative aspects
about different types of energy supplies.
All over the world people talk that we need energy supply that has
no carbon release.
The reality is that it is very difficult to make clean energy.So we have
to look at the demand as well.
We need to find the way to use less energy. And people can do a lot about
it.They can change their habits.

11) http://video.nationalgeographic.com/video/ge-heat-pumps

This video is about ground source heat pumps. Ground source heat pump is
a central heating system that harnesses heat from the ground.
It provides an efficient way to heat or cool your house and provide hot
water, at the same time it needs little maintenance,
and as the heat is obtained from the earth, there is no need for any
fuel delivery.

12) http://www.youtube.com/watch?v=BylLOWRojyY

This is what i get into, i like how it's made. this show lights me up
and teach how things work. it is amazing how little gas and metal give
us light.

13) https://www.youtube.com/watch?v=fO6uebY0gzo
I chose this video, because it is about our country. There is information about Estonians companies which are involved in wind energy. I got to know, that a  very large part of our industry deals with green energy. One of our biggest wind farm is in Narva and also, we have generators offshore. Our country is innovative and rapidly evolving.

14) Nuclear energy is a new source, which if used correctly; it will create a clean source of energy, where the waste will be a million times less.

You can not abandon nuclear power, as it is impossible to approach the nuclear plant and lock it with a key and say that it is no more. Since there is residual heat-selection, which is necessary to remove waste products: waste is plutonium, which should be stored for millions of years, if not to burn the reactor or the reactor and such reactors provide in the future. One type of the current generation of reactors in which uranium-235 is less than oil 2-3 times. If you build a fast neutron reactor, it is an unlimited source of uranium. But still needed besides that fast reactor closed loop as fuel which is discharged from the reactor, it must be processed, rather reused. For example France uses in thermal reactors.

Now there are alternative directions, but the question remains: fast reactor-best on the responsibility of carrying weapons-grade plutonium. Closed cycle is a way out of the huge amount of waste-fuel rather of elaboration extract the most useful and what is the most harmful to create a risk of overall prevalence.

15) Here is link to my video, that i find interesting. This is quite a  short,  but informative video. It is a new type of a windmill, which is easy  and cheap to produce. This is three times more effective, than a conventional windmill. I think it is brilliant idea, because simple things are usually most durable. In future this type of windmills could easily be used to supply households with electricity. I heard about this new technology  from Radio 2.
