Studies have shown that solar energy can supply about 1,000 times more energy than the world’s demand; however, only 0.02% of its full potential is … With recent developments, solar energy systems are easily available for industrial and domestic use with the added advantage of minimum maintenance. Some states also consider low-impact or small hydro, biomass, biogas, and waste-to-energy to be renewable energy sources. Solar energy also plays an important role in diminishing the humidity and killing the harmful germs. Every day, the sun radiates an enormous amount of energy. Of course solar energy can be put to use to heat or light up a room by simply having well placed windows and skylights. In Chapter 21, which is the last chapter of the regular text, we discuss solar fuels, which allow to store solar energy on the long term in the form of chemical energy. Solar energy is a growing industry that can exist in many areas depending on how the sun’s rays hit the Earth (Dincer 2011). x��U�n1}߯�6Һ���1�R@���"�˞s�r��;�$ S��/��jo���C�n��a����� u���z�b� #������1��0�VFd%�X��8�uU#�tY Jjd�Yw�7`�@���y� ;�����I Solar energy is the energy force that sustains life on Earth for all plants, animals and people. ��N�gQk����/Dm(( Ͽ���@iA)]�K&j�� �!�7�z�槈҃�����=qe�Q+�B�=�1������s!j*x�d`�.>N:Y~�Zb����h� b�0������Ҁ5e��;o5Xn'�ڔsRߚ�XI�U��S~ԙ��d�7e��?_O�xQ��[>���(���œ�x�*jI���� ���j���e���I��W���DBѐӞ��Yo��0-���l�nNJ���TW ^r�멄3�� Y��4:�@=Q�L��(��B̜}ѫ�ξV ��������~�z����z���]�� ��oܸC2SyѤ����݌JcQ�~T��m?
