In a general sense, this term means the use of hydrogen as an energy carrier, i.e. as a medium for energy manipulation. In that sense, hydrogen has significant advantages over electricity, which is the most widespread energy carrier today. More precisely, hydrogen energy is the chemical energy stored in hydrogen. Hydrogen economy is an integratedContinue reading “HYDROGEN ENERGY and HYDROGEN ECONOMY”

THINK ABOUT THEM AND TRY TO FIND AN ANSWER. We would greatly appreciate your comments. Question 1: WILL THE WORLD FACE THE THREAT OF NUCLEAR WAR IN THE NEAR FUTURE? Question 2: WHAT are THE MOST- RISKY POINTS? And why?

NOTHING IN NATURE IS, BY ITSELF, GOOD OR BAD. WE ATTRIBUTE THESE PROPERTIES TO CERTAIN PHENOMENA OR EVENTS. THEREFORE, CLIMATE CHANGE IS CONSIDERED HARMFUL TO HUMANKIND BECAUSE IT IS UNABLE TO ADAPT TO THEM AT THE RATE AT WHICH THEY OCCUR.

These changes occur due to the so-called Greenhouse Effect. What Is the Greenhouse Effect? Our planet receives energy from the Sun mostly as ultraviolet (UV), visible (V) and infrared (IR) radiation. About 70% of that energy is absorbed by the Earth’s surface, while the rest is reflected into the Cosmos. The absorbed part warms upContinue reading “CLIMATE CHANGES”

Nuclear energy in the broadest sense originates from the transmutations of the atomic nuclei of a chemical element into the nuclei of other elements, either through the processes of radioactive decay or nuclear reactions. In fact, nuclear energy is the energy that comes from the fission of atomic nuclei, allowing us to produce energy atContinue reading “NUCLEAR ENERGY”

An easy way to roughly estimate how long an energy fuel will last is to divide the proved reserves by the current annual production (consumption). The global data are given below together with the results obtained. However, it does not mean that these estimates will be fully valid in the future. Proved reserves, and especiallyContinue reading “ENERGY RAW MATERIALS – How long will they last”

CONCLUSION NOTES NOTE-1: The share of electric energy in total energy consumption globally is slightly above 15%. However, people often have the impression that it is a much higher percentage. NOTE-2: In the future, the share of renewable sources and nuclear energy will be significantly increased, while energy from fossil fuels will decrease due toContinue reading “WORLD ENERGY NEEDS”
