Disgrifiad o'r gweithgaredd
Gall cystadleuaeth ysgol gyfan godi ymwybyddiaeth o'ch ymdrechion effeithlonrwydd ynni ac annog disgyblion i gymryd rhan yn yr ysgol a hefyd gartref. Rhowch 100 pwynt i bob dosbarth ar ddechrau'r gystadleuaeth. Arolygwch y goleuadau bob dydd ac os gadewir goleuadau yn eu parth neu ystafell ddosbarth benodol ymlaen, caiff pwyntiau eu tynnu o'u sgôr.
