solutions that are good for the individual, but the biggest challenge ahead of us isn't technology, it's public acceptance. it's support for improved permitting and collaboration on changes to ensure that migration patterns for birds are known and we don't site wind turbines in those areas or wind farms in that space. but there can'tjust be a wholesale rejection of this technology because of the threat of something that would be negative. that collaboration is the real opportunity for us to work together. so it's a partnership, really, it's you delivering the technologies that make the future possible, and us adopting them and making the right choices to protect us from this growing threat. thank you so much. we're going to move to questions now. this is the engineers: clean energy. we've been discussing the future of solar energy, wind power and electrical storage, and i'm going to ask who would like to ask a question of any of our clean energy engineers.
