    New sources of energy for the future


    The International Energy
    Agency has delivered a tough and pointed warning to the energy industry. The
    Energy Agency emphasized the fact that investors should not earmark funding for
    new natural gas, oil and coal-based projects any longer, if humankind wants to
    reach the zero-gas emissions target until 2050. It is estimated that, globally,
    gas emissions this year are sure to increase at an alarming rate as global
    economy recovers from the pandemic-generated crisis. Climate-wise, the economic
    recovery occurring in the wake of the COVID-19 crisis is in no way sustainable
    at the moment. The Agency also added that governments worldwide need to move
    fast in order to reduce gas emissions or else we’re highly likely to face an
    even more serious situation in 2022.UN Secretary General Antonio Guterres has
    in turn called on the developed countries to gradually eliminate the use of
    coal until 2030 and stop building coal-fired power plants altogether. All that
    has occurred against the backdrop of an estimated increase in electrical energy
    demand, the fastest in the last decade. There is nonetheless good news to that
    effect, such as the reported increase in the production of solar and wind
    energy in China. By the same token, the government in Berlin has adopted a plan
    meant to speed up the implementation of the climate objectives; Germany is set
    to reach the neutrality of gas emissions by 2045. Actually, the developed
    countries in the last months have ambitiously committed themselves to reducing
    polluting emissions. Such far-reaching pledges need to be complied with. In
    turn, French president Emmanuel Macron shared the belief whereby the African
    states should not be stuck up with the fossil energies. The African states will
    have to make sensible progress to that end, at the same pace with the rest of
    the world. Accordingly, massive investments need to be drawn in renewable
    energies sector. In fact, the appeal made by the French president highlights
    the heart of the matter from the viewpoint of production and the economy.
    Basically, it is all about a groundbreaking change in society and economy.

    Here
    is what Professor Mircea Dutu told Radio Romania:


    In the last
    200 years or so, the progress made by the entire society and the economy on the
    planet has been based on an energy model that heavily relied on fossil fuels:
    coal, oil and gas. Therefore, under the circumstances, in a bid to harmonize
    the economic development with what happens in terms of climate change, the
    option has been made for the change of that fundamental way of producing
    energy, that is doing away with the fossil fuel energy and using the renewable
    energy instead, and, in some case, the nuclear energy, at any rate, such an
    option resorted to energy sources with low greenhouse gas emissions. The stated
    aim of the action to be taken at global level, in a bid to mitigate effects and
    adapt to the ensuing climate change, is, from the sheer climate viewpoint,
    reaching the 2 degree Celsius temperature limit, even 1.5
    Celsius degrees, if possible, as against the reading levels prior to the modern
    age, the pre-industrial age, that is, and concurrently but definitely
    concertedly, reaching the climate neutrality level in mid-century, all that as
    a component of the action humankind takes in order to comply with the set
    target of reaching the average temperature limit at global level.


    To what extent human
    activities have accelerated changes in climate at global level, as of late? To
    a great extent, certainly. And we are even more accurate stating that than we
    were 10 years ago, or at least that’s what climate expert Roxana Bojariu says.
    According to the most recent report of the Intergovernmental Climate change
    study group, human activities have caused 95% of the reported increase in
    temperature readings beginning the second half of the 20th century.

    Roxana Bojariu:


    These are numerical
    experiments, they are the perfect equivalent of the physics lab experiments
    revealing the fact that, unless we take into account the increased
    concentration of the greenhouse gas emissions, we will not be able to obtain
    the upward trend of the average temperature reading at
    global level.
    So the natural factors do not have any effect whatsoever on
    the creation of the upward trend of the global average temperature reading,
    basically. The activity of the sun, the volcanic activity, they cannot explain
    that overwhelming increase either, we can all see records are set from one year
    to the next, from one month to the next. The last six years have been the
    warmest six years in terms of recorded temperature readings, beginning the
    second half of the 19th century. The last decade was the warmest of
    all decades for which temperature readings have been recorded. But these
    all-time high temperature readings go with extreme phenomena, record-highs in the case of
    several manifested phenomena. Last year, we recorded the hurricanes’ most
    active season in the Atlantic. Concurrently, we have an accelerated melting of
    the ice layer in Greenland, but also in western Antarctica. Unfortunately, such
    phenomena are highly likely to intensify in the future. Fires will break, like the
    ones we had in Australia but also in the Amazon, in much the same way as we had
    fires that flared up in southern Europe. Numerical experiments even point to
    the fact that in Romania, vegetation fires will unfortunately have an increased
    impact as the upward trend continues in the case of the global average temperature
    readings, as the ongoing change expands .


    As for the climatic
    neutrality, we need it by 2050. Which means that all our activities that
    eventually lead up to emissions in the atmosphere must be balanced out. All
    things considered, we need to have net zero emissions, so that our imprint, the
    imprint our activities have on the environment, all that should no longer
    exist, according to climate expert Roxana Bojariu.
