Yes! First of all, congrats on embarking on learning about Wicca and putting your study into practice!
We had a topic about Sage and Candles in Apartments. This was my reply there:
Today, more and more churches and temples are introducing features like electric candles, complete with flickering flames. Electric votive candles have long been in use in military chaplaincies.
Remember that the Magic is not in the ingredients or the tools but in the Witch! 
Every ingredient has a substitute as long as your intentions are clear and in line with your will.
