a breakthrough in the provision of energy from the sun for the european union (eu) could be brought forward by up to two decades,if a modest increase could be provided in the eu’s research effort in this field,according to the senior eu scientists engaged in experiments in solar energy at eu’s scientific laboratories at ispra,near milan.
the senior west german scientist in charge of the eu’s solar energy programme,mr. joachim gretz,told reporters that at present levels of research spending,it was most unlikely that solar energy would provide as much as three per cent of the eu’s energy requirements even after the year .but they said that with a modest increase in the present sums,devoted by the eu to this work it was possible that the breakthrough could be achieved by the end of the next decade.
mr. gretz figures out that if solar energy only provided three percent of the eu’s needs,this could still produce a saving of about a billion dollars in the present bill for imported energy each year.and
he believes that with the possibility of using more advanced technology in this field it might be possible to satisfy a much bigger share of the eu’s future energy needs.
at present the eu spends about ＄2.6 million a year on solar research at ispra,one of the eu’s official joint research centres,and another ＄3 million a year in indirect research with universities and other independent bodies.
5.()according to mr. gretz,the present sum of money will enable the scientists to provide ________.
a.more than 3% of th eu needs after the year
b.only 3% of the eu needs before the year
c.less than 3% of the eu needs before the year
d.only 3% of the eu needs even after the year
