      21世紀になっても空は曇るし夜は来る。風も一定ではない。自然エネルギーでも地熱や大規模水力なら安定供給が可能で、エネルギー密度も太陽光や風力より高い。でも環境団体は消極的。駄目なものばかり推すのは、環境左翼が社会を混乱させて革命を狙っているためか。https://twitter.com/YohYasuda/status/1176830012445450240 …

      更に付け加えると、「太陽光や風力は出力が不安定なので」という枕詞は20世紀の発想であり、その時点から知識や技術が進歩してない人や国は、21世紀を生き残ることができないと思うよ。グレタさんに対してマウントを取りたがる発言って、勉強不足なものが多いよね。

      何度も言うが、エネルギーの議論をするなら、高校の理科ぐらいは勉強して欲しい。時代が変わっても科学の法則は変わらない。単位を理解して数値で議論できれば、蓄電池の容量が我々が普段使っている電力量に比べて極めて小さいことはすぐ分かる。化学を知っていれば燃焼熱と電池の容量を比較できる。

          経済学の知識だけでエネルギー問題は議論できない。なぜなら、どれだけ多くのお金を研究開発に投じても、科学の法則に反するものを作ることはできないから。だから、高校の理科ぐらいは勉強しないと、エネルギー政策についてまともな議論はできない。
