Rowan Energy is the world's first community supported green energy blockchain. Based on the low powered POA consensus mechanism, which uses certificates to authorise transactions rather than utilising traditional energy hungry mining. They are building a series of Energy focused apps that bring the Energy Market into the 21st Century, decentralising and digitising a traditionally archadic industry. .
Rowan Energy airdrops up to 55 RWN tokens (~$24,75) to their airdrop participants for the following simple tasks. They also offer a referral program where you can earn additional RWN for each user you refer.
