Looking at this land from the sky, you see roof of apartments or flats and office buildings.</p> <p>In opposition wards like Potong Pasir, there are some small implementations of solar-powered lamp-posts.</p> <p>Why stop there?</p> <p>I urge WP to champion the implementation of solar panels on all ROOF TOPs of HDB flats.</p> <p>This power is channelled back to the grid.</p> <p>Imagine whole island is covered by solar panels the amount of free electricity that can be produced. It will be astonishing! believe me.</p> <p>I know some can say that solar panels are expensive. Not as before. Take into consideration the economies of scale, even less expensive. Take into consideration the minimum maintenance required for the panels,&nbsp; you will start to get the picture. Consider how long these panels can last, your eyes and minds shall begin to open up.&nbsp; Expensive? What is expensive?&nbsp; Going green, what is expensive? Longterm view, what is expensive? Waste of solar energy, is that not a HUGE WASTE? which is worse?</p> <p>I hope the WP champion this and make it their contribution to singapore.</p> <p>Do the needful. Do the right thing.</p> <p>Go for the green vote.</p> <p>Thank you.</p> <p>Gutentaginator</p> <p>&nbsp;</p> <p>&nbsp;*edited : the word "longtime view"&nbsp; into "longterm view"</p> <p>&nbsp;</p> <p>&nbsp;</p> Sun, 15 Jun 2008 10:53:39 +0800 sgforums.com:10:321009:8167146 Gutentaginator http://sgforums.com/forums/10/topics/321009
